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

Yep, a default function is passed to wrap and in most cases blub just
calls that one.
But sometimes I need blub to use a function other than the default one.

Don't know it this is the right answer or a possible bug but it does the 
trick:

void h() { import std.stdio; write("h()"); }

class Bla
{
    mixin wrap!h;
}

mixin template wrap(alias f)
{
    void blub(typeof(&f) g = &f)
    {
        g();
    }
}

void main()
{
    Bla b = new Bla();
    b.blub();
}
