Started adding support for return checking and non-returning function annotations * Reorganized typestate into several modules. * Made typestate check that any function with a non-nil return type returns a value. For now, the check is a warning and not an error (see next item). * Added a "bot" type (prettyprinted as _\|_), for constructs like be, ret, break, cont, and fail that don't locally return a value that can be inspected. "bot" is distinct from "nil". There is no concrete syntax for _\|_, while the concrete syntax for the nil type is (). * Added support to the parser for a ! annotation on functions whose result type is _\|_. Such a function is required to have either a fail or a call to another ! function that is reached in all control flow paths. The point of this annotation is to mark functions like unimpl() and span_err(), so that an alt with a call to err() in one case isn't a false positive for the return-value checker. I haven't actually annotated anything with it yet. * Random bugfixes: * * Fixed bug in trans::trans_binary that was throwing away the cleanups for nested subexpressions of an and or or (tests: box-inside-if and box-inside-if2). ** In typeck, unify the expected type arguments of a tag with the actual specified arguments. 2011-05-14 21:02:30 -05:00			`// -- rust --`

Finally rename std::_xxx to std::xxx Except for _task, which is still a keyword. 2011-05-17 13:41:41 -05:00			`import std::vec;`
