Previous version used
_testlist_comp
which allowed for either onetest
or 2 and moretest_or_star_expr
.This version also allows a list with one
star_expr
which is valid both in Python and in official Python grammar.Moreover it merges rules used in
set
andlist
(since those terminals differ only in that set literal cannot be empty)
