Does xcore support generics? I have some issues, see below for example:
package test
class A<T extends B> {
contains T b
local refers derived T derivedB get {
b // I get this error: Incompatible implicit return type. Expected T but was T
}
}
class B {
}
Thanks,
David

David,
That seems odd, but looks like an Xbase problem. Please open a bugzilla.
