There may be something to be said for caching "common" floats, like pi,
small integers (0.0, 1.0, 2.0, ...), 0.5, 0.25 and similar, but I doubt
the memory savings would be worth the extra complexity.
I've read some time ago, that simply caching 0.0 reduced appreciably the
memory usage of a Zope application.
(Note that Zope relies on pickling and unpickling objects all the time, so
even if two objects started as the "same" zero, they may become different
at a later time.)
