Is this a bug? If not, how do you make it work?

void h() {}

class Bla

mixin template wrap(alias f)

        {

void main()

test.d(18): Error: template instance test.Bla.wrap!(h).blub!(f) error

I've seen this error before...

Here you go: http://d.puremagic.com/issues/show_bug.cgi?id=3051

As a workaround, is there a reason you need blub to be parameterized?  I  
mean, f is already part of the template.
