7b12924813 Fix pretty-printing of istr literals. Issue #855 2011-08-23 11:09:38 -07:00
Brian Anderson
152cbaade7 Move functions from syntax::ast to syntax::ast_util 
This leaves syntax::ast just defining the AST, which strikes me as somewhat
nicer

7d08678b74 Implement pattern guards 
The syntax is

    alt x {
        mypat where mycond { ... }
    }

The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.

Closes #857

b24f978011 Drop arguments on the caller side, not the callee 
This makes it easier for the caller to optimize the take/drop away for
temporary values, and opens up new possibilities for alias handling.

Breaks tail calls.

84fb821e40 Try harder to disambig blocks followed by various exprs in pprust. Closes #840 
As it turns out, it's not just unops we need to worry about. Also tuples and
anything that requires parens.
