e824775d53 Remove std::str. Issue #855 2011-09-01 16:09:15 -07:00

6ba4eacddf Make resolve recognize upvars 
Upvars are now marked with def_upvar throughout, not just when going
through freevars::lookup_def. This makes things less error-prone. One
thing to watch out for is that def_upvar is used in `for each` bodies
too, when they refer to a local outside the body.

f841e89443 Support unchecked blocks 
This patch supports the syntax

    unchecked {
      ...
    }

    to disable purity checking within a block. Presumably it will only be
    used within a declared "pure fn". However, there is no checking that it
    doesn't occur elsewhere, and it would be harmless for it to do so.

    I went with Lindsey's suggestion for the syntax, but it's subject to
    change.

    This allows you to write code that uses predicates that call arbitrary
    Rust functions, but you must declare your intentions by wrapping it in
    an unchecked { ... } block. The test case run-pass/unchecked-predicates.rs
    demonstrates how to do that.

c6155d1fd1 Change "pred" to "pure fn" (but still accept "pred") 
This is part 1 of changing the "pred" keyword to "pure fn".
Right now, the compiler accepts both "pred" and "pure fn".

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

This changes the indexing syntax from .() to [], the vector syntax from ~[] to
[] and the extension syntax from #fmt() to #fmt[]

67e361a940 Introduce a ty_infer ast node and use it instead of option::t[ty]. 
This actually basically makes things worse, since we get less nice
type system guarentees but it will make doing type inferred blocks a
fair deal less painful. I'm not /really/ happy about this...

985c32ef4c Partially implement destructuring locals 
You can now say

    let {bcx, val} = some_result_returner();

Similar for loop variables. Assigning to such variables is not safe
yet. Function arguments also remain a TODO.
