IIUC, Micro Python already has a few differences -- but is anyone saying they shouldn't call it Python? Though, with a quick perusal of teh docs, micro Python does seem to support NaN and Inf, at least -- not sure about the rest of 754. While we're at it are 64 bit floats required for either cPython or Python the language? IIUC, the main platform that this was an issue for, for computationally heavy code, was Cray -- but it seems they're 754 compatible now, yes?
