Right, but enums could possibly be a lot richer than class constants are
now.
They could be a type where the only values are what's defined in the enum.
This could be used with type hinting:
enum Foo {
A,
B,
C
}
function bar(Foo $x) {
// ...
}
There'd be no need to do any manual checking that $x is a valid value.
Perhaps enum values could also be casted back to strings:
(string)Foo::B; // "B"
Sure, this is the kind of stuff that's possible in other ways already, but
first class support always helps.
