The current syntax-rules implementation generally works, but leaves a little to be desired. Namely:

  • No support for quoting of the ellipsis character (... ...)
  • Matching of patterns with ... and . should be greedier with the repeat? Not sure about this one.
  • What if the ellipsis is also a literal identifier?
  • Macro hygiene
    • Identifier hygiene
    • Scope hygiene
  • Missing location on expanded templates.
  • Substitutions inside quoted templates.
  • Vector patterns and templates (#(<pattern>+)).
  • Macros are not included in compiled libraries.
  • Re-export of macro items.

Another thing here is we parse templates and patterns with the same code. Templates can have arbitrary repeats. Patterns only one per form.
