I'd like to do something like

alias CR(t) = Complex!double(t);


CR(3)

which would be equivalent to typing Complex!double(3) but much 
shorter.

Writing a wrapper is overkill.

I guess I oversimplied... alias C = Complex!double; then C(3) works fine. My problem is slightly more complex but I haven't figured out how to reduce it.
