Cool. Didn't know you can do that, but I guess it makes sense that it
would work that way.
The only thing I wish for is if I didn't have to explicitly define what
T and T2 were and I could just do
foo!(bar)(1,2);
The following works and is news to me. Apparently template parameters
with default values need not be at the end of the template parameter
list:
void foo(alias thing = (){}, T, T2)(T a, T2 b)
{
thing();
}
void bar(){}
void main()
{
foo!(bar)(1,2);
}

This means that D can simulate Ruby blocks more than I thought. That's
pretty awesome. I'm loving D more every day.
How's that like a Ruby block?
