Anarki now permits postfix '!' in symbols
1 point by akkartik 1389 days ago | 4 comments
Before:

  arc> a!
  Bad ssyntax: a!
After:

  arc> a!
  Error: _a!: undefined
In the process I've also tightened up ssyntax in general, so that prefix/postfix ':' doesn't go through ssyntax expansion, etc. Some errors will now simply silently fail to transform.

How do people feel about this?

Edit: I did this to reclaim scheme's '!' suffix for destructive operations, in particular for def and mac. A brief prior discussion about this: http://arclanguage.org/item?id=12505

If you support symbols like a! then what about ssyntax like a!.foo?

  arc> foo!.3
  Error: "Bad ssyntax foo!.3"
That doesn't seem too bad, IMO: if your sym uses ssyntax chars you can't use it in ssyntax. There's probably worse corner cases I haven't considered, though :/

Never mind, I rolled all that back and renamed def! and mac! to redef and remac, respectively.

Thanks for changing it back, but thanks for taking a leap there too. :-p
