[Numpy-discussion] complex comparisons

[Perry Greenfield]

Let me throw my 2 cents in as well. As Paul mentions this has been 
discussed before. It seems nonsensical to allow these comparisons since 
there is bound to be some confusion about their meaning no matter what 
is chosen. And if someone would like their code to be generic with 
regard to complex numbers and regular floats, then they should use 
.real, .imag, and abs() explicitly to be precise about what they are 
comparing. All these will work with both kinds of types.
