Commit Message

Markus Armbruster Sept. 28, 2019, 6:39 p.m. UTC 
Split check_name() into check_name_is_str() and check_name_str(), keep
check_name() as a wrapper.

Move add_name()'s call into its caller check_exprs(), and inline.

This permits delaying check_name_str() there, so its error message
gains an "in definition" line.
