Sounds like a good idea. Complex math is probably only used in a very 
small subset of D code, and if most advantages of having the types built 
in are rendered irrelevant I see no reason not to take this opportunity 
to simplify the language.

Regarding literals, I'd say this is would be an adequate replacement for 
the above expression:

	3 + 5*i

And last, getting rid of the creal and ireal keywords can only be a good 
thing. :)
