std.complex needs be to firmly established as a complete replacement
for creal et. al, before they can be declared deprecated. We're not
there yet (writefln of complex numbers didn't work in the last
release).
Even when it happens, functions like writeln should behave a bit more
gracefully. Does it do the same thing with other unusual types?

It's also worth noting that moving associative arrays to a library
type has been very painful. Nearly ten releases later, we still have
some horrible regressions. Doing the same thing with complex needs to
be done very carefully.
