You can't remove only half of a feature of the language, so I don't like this
idea.
I accept to remove them fully if their semantics can be fully replaced by the
std lib. Otherwise just let Don fix the broken things.

It's not necessarily "removing half a feature". Imaginary numbers aren't
closed under many operations. The idea is that imaginary literals are
turned into complex. So "ireal x = 10i;" becomes "creal x = 0 + 10i;".
Since complex numbers are closed under all the builtin operators, it
eliminates many of the problems (casts from complex to real).
Putting it in a library eliminates the ability to use complex/imaginary
literals (unless it's a runtime type).
