Remove proto_sugar and 'lambda' as keyword, commit to fn@. 2012-01-09 18:12:37 -06:00			`fn test(f: fn@(uint) -> uint) -> uint {`
Convert ret to return 2012-08-01 19:30:05 -05:00			`return f(22u);`
impl the proper partial order between fn types 2011-12-16 15:50:22 -06:00			`}`

Cleanup how we handle proto in types, remove unsound subtyping Fixes #1896 which was never truly fixed, just masked. The given tests would have failed had they used `~fn()` and not `@fn()`. They now result in compilation errors. Fixes #2978. Necessary first step for #2202, #2263. 2012-11-04 22:41:00 -06:00			`log(debug, test(f)); //~ ERROR expected @ closure, found ~ closure`
Use singlequotes in the typechecker too, to distinguish code and English 2011-12-25 13:27:09 -06:00			`}`
