Ugh, that's a compiler bug.
You should not be able to pass in delegates as function
pointers to a mixin template.
A better way would be to pass in the names of the methods into
the mixin template and then use string mixin's to call the
methods.
Better yet, try this:
mixin template Template(void delegate() func1, void delegate()
func2)
