There was an exchange on IRC last week about removing some keywords. It
seemed a bit too broad and open-ended to open an issue for it, but I
didn't want it to get lost entirely.
pcwalton:we could get rid of "resource" and "be", maybe "while" and
"log", although "trait" will add another
pcwalton:maybe unifying import and use like we talked about
graydon:'as' can go if we pick up go's expr.(type) syntax
pcwalton:yes
pcwalton:I like that syntax
graydon:is 'tag' still listed? looks like in my docs. it should be
'enum' now
pcwalton:"note" might be better done as a special kind of class
pcwalton:just RAII-based
pcwalton:notes sitting on your stack print themselves out during
unwinding, but hide otherwise
graydon:maybe. that's how it was done in monotone (where I copied the
feature from)
graydon:'block' is a dead keyword, you can remove that
graydon:as is 'obj'
graydon:'syntax' is likely to prove redundant, or might if we shift
around the order of evaluating attributes and/or make "activating a
compiler plugin" something you can do via attributes.
graydon:pcwalton: 'in' is also dead, I think. 'with' could probably be
turned into something symbolic w/o much work.
Based on this conversation pcwalton, niko and I filed a bunch of new
papercut issues:
* Remove `be`
https://github.com/mozilla/rust/issues/2227
* Implement `assert` in the library
https://github.com/mozilla/rust/issues/2228
* Rename `cont` to `next`
https://github.com/mozilla/rust/issues/2229
* Remove `do` loops
https://github.com/mozilla/rust/issues/2230
* Use go's casting syntax
https://github.com/mozilla/rust/issues/2231
* Implement `fail` in the library
https://github.com/mozilla/rust/issues/2232
* Remove `while`
https://github.com/mozilla/rust/issues/2233
And here are some old ones that cover the same territory
* Implement `log` in the library
https://github.com/mozilla/rust/issues/554
* Implement `note`
https://github.com/mozilla/rust/issues/415
