Numeric types should have the equality (== and !=) and ordering (< > <=
>=) operators - this should be working now in the codebase.

Strings and booleans should probably also work with the equality (== and 
!=) operators.

Any numeric type should work there.

There is a bug related to this, bug 126: 
http://bugzilla.mcs.anl.gov/swift/show_bug.cgi?id=126

That is a problem in the runtime, that can be fixed separately from 
typechecking.
