std.complex

[eles]

actually, i think 2.045 was the second (after 2.044) release to
include std.complex.

as i understand, std.complex should replace the native types cfloat,
creal, ifloat, ireal etc.

i was eager to test the new std.complex. it seems that some work is
still needed. maybe someone could submit a bug report?

otoh, native types creal, cfloat etc. are not deprecated, it seems.
they should be, i think.
