Hi! I was asked by Kirill to review this patchset, so here my
review turns up. See 3 comments below.

1. Why 2645? I do not see where do you check types
in the parser. Also, Kirill said that it is relocated
to 2.1.1/2.2.0 (I do not remember exact milestone).

2. Is 3459 fixed? I do not see its mention in the
commits.

3. selectA.test.lua consists of 2536 lines. Why 10k? What is a
problem to convert it manually?
