: 1. How to use this mode? I mean,
: ./test-run.py sql-tap/e_casts.test.lua --verbose
: gives a lot simpler result that I expect from this much of code.

For debugging of various failures I run it directly via script as simple as
that:

20:05 $ ~/bin/sql-tap-run.sh sql-tap/e_casts.test.lua -v | head -40

I need to see those tables (explicit and implicit) visualized to make 
sure I have them correctly entered and be compatible with written to RFC.
This output is incompatible (and unnecessary) for TAP mode, that's why it's 
not activated by default.


: 
: 2. What means e_casts? If it is for explicit casts, why not name it
: something
: like "explicit_cast.test.lua".

Because it's not planned to be only about explicit casts :)
[You'll see it's development in the next version of patchset]

And this strange e_* prefix is inherited from the times when I wanted
to resurrect e_expr.test.lua Now, having asked about it, I do realize
it makes no much sense and probably should be removed.

Will rename to sql-tap/casts.test.lua

: 
: 3. As far as I remember, "sometimes" doesn't mean that CAST(1.0 as UNSIGNED)
: can return 1 or can throw an error. It means that there are rules that
: define
: when values of one type can be converted to values of another type. So,
: instead of checking failures for "maybe" we can check that "from" value
: should fail or not according to these rules and use proper test.

Yes, sometimes meant that some part of data might be safely converted, but
others will not. And here we should prepare proper set where some values
are valid for conversion and others are not. (See my answer below)

: 
: Also, using this approach we can try to use randomized "from" values. Just
: thought.

I thought about it some day, but no, randomized data will introduce unnecessary
volatility to testing and will not add any extra value to this particular case.
A well prepared data-set provides here much better results, when we
actually check only compile time reactions, and not run-time.

Though, eventually this approach might be modified for fuzzing of this part
of code, and there randomization will be necessary, but not today.

: 
: 4. Why you test only literals? Nothing indicates that values from spaces
: shouldn't be tested here.

At the moment of writing this patchset I've not yet figured out how to
conveniently deal with generated fields of expected types. Now, for implicit
conversion type I do have easy approach, and will add this case for run-time
explicit conversion of different type expressions.

: 
: >
: > Relates to #5910, #6009
: > Part of #4407
: 5. Wrong issue number. Also, I still think that "relates to" is not
: needed here.

Yup thanks for the catch about 4470! [But I'd still keep relation to
consistent-type spec - that's part of larger work]

: 6. What point to use sqltester here is you do not use its functions? You
: can use
: 'tap' instead.

Good point - sqltester is not used here.

: 8. Is there any point to use ffi here? Can't you use something simpler?
: For example:
: local types = {
: 	any		= 0,
: 	unsigned	= 1,
: ...
: 
: Than instead of t_any you can use types.any and so on.

Originally the point was to just copy-paste the definition from Tarantool
code as-is, without any massaging or modifications.

[Ideally it should be extracted from the actual code src/box/field_def.h code. 
And I'll probably do so, eventually, because field_def.h is prepared for such
extraction, and this place is marked with /** \cond public */ 
/** \endcond public */ boundaries, so enum could be easily extracted]

: 
: If you start from 1 instead of 0 you can also use type_names instead of
: proper_order.

At the moment I don't consider that getting rid of ffi.cdef will simplify
anything or provide any extra value.

: 9. I think it is better to check them for "wrong type name" or remove these
: types.

I don't quite get what is "check for 'wrong type name'"? Could you please elaborate?
(Those unused type will be added in the nearest times, in any case)

Because this is actual copy-paste from original xls on which RFC was based on.

: 12. I believe word 'table' is reserved for in Lua. Not sure that it is good
: idea to overwrite this reserved word.

Apparently it's not reserved and we could reuse it as identifier in
local context. But thanks for reminding - that would be very confusing 
the moment I'd need to use table.insert or something. (Strange that luacheck
which is always activated in my vscode editor did not complain here a lot)

: 13. Do you need this function? You can just expand gen_type_samples
: using its
: code.

Function allows to avoid copy-paste for values from meta types such as
Number and scalar. 

: 
: This comment can be implemented for some other functions, for example
: the next
: one. I think it will make code simpler to understand.

[If I correctly understood your sentence] Nope, copy paste will make 
code much more verbose, and less observable.
