This could be:

    getResponse!(Point!int)

or:

    (getResponse!Point)!int

D requires this to be disambiguated at the parsing stage, 
before the compiler works out what getResponse might be.

An example of the latter:

template getResponse(alias n)
{
    alias getResponse = n;
}

getResponse!Point is just Point.

I'm not sure why that tutorial has it wrong, but the way to get 
it fixed is to contact the author.

Thanks! I had some issues with the syntax, and getting that part 
correct got me to the conceptual bits, which is where I got lost 
for real. Syntax errors are such a drag, though.

Appreciated.
