How is this code supposed to work?

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.
