# From 3.5.1 bdb
#
# RETURN_VALUES can get turned in RETURN_END_IF
# scanner3's detect_structure sometimes can't
# fully handle Python 3.5's jump optimization
# So in 3.5, for now, we allow:
#
#    return_stmt ::= ret_expr RETURN_END_IF
# and you see that in the grammar rules for below.

# For other pythons the RETURN_END_IF may be a
# RETURN_VALUE.
# Or it may be that we may want to add that
# additional return_stmt grammar rule for Pythons
# before 3.5 which currently isn't needed.
