Classes with dtors should compile now. Haven't yet tested
whether they actually run correctly.
Beginnings of support for #2295, though that won't be done until
there's more test cases and resources are removed.
- paths can now take region parameters, replacing the dirty hack
I was doing before of abusing vstores. vstores are now a bit
of a hack though.
- fix various small bugs:
- we never checked that iface types were compatible when casting
to an iface with `as`
- we allowed nonsense like int<int>
- and more! (actually that may be it)
Adds a new kind of pattern C(*) where C is a constructor that may
have any number of fields. This pattern matches any value
constructed with C, without binding names for any of the fields.
Closes#1701.
Introduce syntax like:
iface animal { ... }
class cat implements animal { ... }
to allow classes to implement ifaces. Casting classes to ifaces
is *not* yet supported. ifaces that a class implements are not
yet included in metadata.
The syntax is subject to change, and may go away completely if we
decide to use duck typing to relate classes with ifaces (see
http://smallcultfollowing.com/babysteps/blog/2012/04/10/declared-vs-duckish-typing/ )
Classes can have ty params now. So can methods inside classes.
That was probably true before, but now it should still work if you
call methods in a class that's defined in a different crate. Yay!
