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.
