Changes for version 0.100
- Refactor the logic that discovers which variables are interpolated into double-quotish strings into PPIx::QuoteLike. This does not include regular expressions, which are already handled by PPIx::Regexp.
- Survive variable declarations that declare nothing. These can appear if (e.g.) PPI mis-parses an attribute list, and that attribute list contains something like 'Arg(state)'.
- Perl::Critic::Policy::Variables::ProhibitUnusedVarsStricter - Don't ask for storage you don't need.
