Make _\|_ unify with anything The typechecker had a number of special cases for unifying types with _\|_ (as with checking if and alt). But, a value of type _\|_ should be usable in any context, as such a value always diverges, and will never be used by its immediate context. Changed unify accordingly, removed special cases. 2011-05-26 20:14:00 -07:00

Reformat This changes the indexing syntax from .() to [], the vector syntax from ~[] to [] and the extension syntax from #fmt() to #fmt[] 2011-08-19 15:16:48 -07:00			`let i: int =`
Allow omission of the '.' after nullary tag patterns This commit allows patterns like: alt x { some(_) { ... } none { } } without the '.' after none. The parser suspends judgment about whether a bare ident is a tag or a new bound variable; instead, the resolver disambiguates. This means that any code after resolution that pattern-matches on patterns needs to call pat_util::normalize_pat, which consults an environment to do this disambiguation. In addition, local variables are no longer allowed to shadow tag names, so this required changing some code (e.g. renaming variables named "mut", and renaming ast::sub to subtract). The parser currently accepts patterns with and without the '.'. Once the compiler and libraries are changed, it will no longer accept the '.'. 2012-01-14 16:05:07 -08:00			`alt some::<int>(3) { none::<int> { fail } some::<int>(_) { 5 } };`
Register new snapshots, purge log_err and log_full in favour of log(...). 2011-12-22 17:53:53 -08:00			`log(debug, i);`
Port the tests to the expr foo::<T> syntax. 2011-08-13 00:10:18 -07:00			`}`
