Just an idea: What about template-aliases and typedefs

alias(T) OherTemplate(T, T, int) MyAlias;

MyAlias!(double) foo;

The 'class Foo(T)' template form is a shorthand for:

template Foo(T) {
    class Foo {
       ...
    }
}

So, if you want a template typedef, you just do:

template MyAlias(T) {
    alias OtherTemplate!(T, T, int) MyAlias;
}

MyAlias!(double) foo;

Kinda cool that D gets things that haven't even made it into C++, merely 
as a side effect of its design. :)
