[swift-evolution] [Proposal] Refining Identifier and Operator

[Jonathan Hull]

I also need upside-down question mark and exclamation point:  ¡ ¿

¿If the right side up versions are operators, why not the upside-down versions?  I am using them because they are easy to type and my grammar calls for both ? and !, which are already in use by swift.  Using ¡ and ¿ is an easy translation when typing in from research papers (which use ! and ?).  I have quite a few projects dependent on these, and I don’t think they would ever be confused with identifiers… so why ban them?

Thanks,
Jon
