Why do you think it isn't safe, Antoine?
We only support IEEE platforms, and IEEE defines positive 0.0 to be all bits cleared.
I personally don't think that even a small measurable performance degradation in creating new floats is problematic since that is not where typical cpu power is spent. But this is the second time I´ve made this suggestion (the first was on python-dev) and in both cases I've run up against the opinion that it is a "rare" problem and worries about "performance." Yet this seemed not to be an issue when ints/longs were united.
So, while I was recently prompted to resubmit this suggestion, I feel no need to push the matter further and am just letting it rest here, then. I'm sure someone will think it is a good idea again in the future and can then reopen it.
