generic mixin

[gauthier]

I don't know if this should be supported, but for completeness of weird syntax tests:

mixin IsOk<of T>
    var isOk as bool is public
    def getFoo(v as T) as T
        return v
class Ok adds IsOk<of int>
    pass

namespace MixinWithinNamespaces
    class Program
        shared
            def main
                ok = Ok()
                print ok.isOk
                #print ok.getFoo(1)

will get the following compile error

Code: Select all

test.cobra(4): error: Cannot return T because "getFoo" is declared to return a int.

As you've discovered, the mixin support is incomplete. Some of this is documented at the mix-in wiki page. Nevertheless, thanks for the reports.

I probably won't get to this soon as there are a number of small items and patches I'll attend to first.

I missed the wiki page, sorry about that.

So I updated it to state theses limitations, I'm going to work arround theses in my code
