I just came across a problem with the intention to specify unset boundaries given to numpy.clip() or array.clip():
a.clip(1e-10, None) a.clip(None, -1e-10) When doing this, the returned array is dtype=numpy.object, seemingly None gets converted to a numpy.asarray(None, dtype=numpy.object), and this is then used for the comparison. Since (*any number* > None) is true, and (*any number* < None) is false, it works or not, depending on the usecase, despite one is still left with a dtype=numpy.object array. Precisely, using None as the lower boundary semi-works, while using None as the upper boundary doesn't match expectations at all. One can work around this, sure, but in my opinion it would be handy anyway to have clip() interpret None as argument as \pm \infty. Maybe I'm just missing the appropriate function, though.
