Description

I'd like to see ligatures for Perl matching operators, specifically:

  • "<=>" → "⟺" (3 chars wide)
  • regex match, "=~" → "≂" or "⋍"?
  • regex non-match, "!~" → same, struck through?
  • smartmatch operator, "~~" → (double tilde)?

Research direction

The issue requests Perl ligatures for <=>, =, !, and ~~ but leaves several glyph designs undecided and names no files or tests. Start by resolving the proposed glyph forms with the project maintainers, then identify the font source and validation process; done means all four operators have agreed, legible ligatures.
