Is there any difference between using `a ^^ b` and `pow(a,b)`?
I have 3 comments (if you're still reading this thread :) )
First, you could let nextGen determine the return type. Since the
template know that nextGen returns an int delegate(int), there is no
need for the user to provide the 'int' parameter.
So user code could become:
void main(string[] argv)

Most uses of the 'is expression' allows using a specifier to
name the entity that matched. So, inserting ReturnedDelegate in
your '== delegate' line gives the name ReturnedDelegate to the
delegate.
That name can be used further:

Even so, I would still want static if, so that I would get a compile
