Typo should be stripped.

This is a very concise way to do what I want to do, but this check cares
about other attributes of the function/delegate, i.e. if the function or

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:
template exT(T, alias nextGen)
if (

My question is hopefully short and straightforward to answer, but
it's also a two-parter.
I am working on a template that generates a function that
implements an algorithm using several helper functions that are
provided to the template by the user. I would like to add
constraints to the temp
