Allow binary +/- for complex numbers? about patma

Not worth the ink.

Yes. I think to recall that we already mentioned somewhere that we need to allow + in complex values, but I cannot find it anymore. + and - should both be legal in order to form numeric literals.

Cool. This will realistically include binary - as well, to allow each of:

• 1+2j
• 1-2j
• -1+2j
• -1-2j

Sorry for reraising this, but are there actual use cases for these? In general equality matching with floats and complex are problematic (and the values you'd likely want liko 0, 1, 1j, do not require binary ops). Removing this could simplify a bit
