-- Variable info in runtime type errors, per dialect: constants are named
-- from 5.2 (but not as a binary operand before 5.4, which PUC takes
-- straight from the constant table), `t[1]` is "integer index" only from
-- 5.4, an indexed upvalue table (`_ENV`) is named, and 5.4+ name the
-- generic-for iterator.
