Fixes #6318
The following is no longer a syntax error:
While an empty case doesn't make much sense in regular code, it is useful for automatically generated
when
branches (for example in a macro) and avoids extra effort to prevent empty case nodes.This also fixes a parsing error for
case
without condition (case; when true; end
) and adds specs for this.
