Sergey,

Thanks for the patch! I can't understand why this patch is separated
from the previous two (10 and 11). Could you provide a rationale for
this, please? Also consider the comments below.

On 26.03.21, Sergey Kaplun wrote:

Minor: Did LuaJIT always respect such behaviour? If no, please mention
the commit where it has been changed.

As we discussed before: s/Closes/Resolves/.

Side note: What is the difference between #5712 and #5694? They look
like duplicates to me, and so provide another rationale for squashing
all three patches into a single one.

Why did you drop the assertions above? They are trivial (as many of
others in this suite), but still check that everything is fine (e.g.
that <select> yields a number).

Why didn't you create the same structure as elsewhere above? Why did you
change <self> indexing? AFAIU, after creating the *right* <arg> variable
everything should work with no other changes.
