Macro Woes Tracking Issue

[iwillspeak]

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
• [x] 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.
