If you need to compare a `~str` against a constant string, use .equiv():use core::cmp::Equiv; fn main() { let x = ~"foo"; if "foo".equiv(&x) { println("yep"); } } This should admittedly be imported by default.
Really? Strings can't just be compared with == ? To be honest, that alone is almost enough to put me off the language -- not only is it ugly and unwieldy, but it suggests a lot of limitations in the language's memory model / type system / operator overloading, which would also make my own code ugly and unwieldy.
What's the problem with ==, or the difference with equiv(), exactly? Is there some way to make it just work, no matter what kind of strings you're comparing? Perhaps "foo" == (*x) would work, for example?
