That seems to be what happens with other folded constants:

py> def f():
...     return 99.0 + 0.9
py> f.__code__.co_consts
(None, 99.0, 0.9, 99.9)

so I guess that this is okay for a first draft. One difference is that 
strings tend to be much larger than floats, so this will waste more 
memory. We ought to consider removing unused constants at some point.

(But not me, sorry, I don't have enough C.)

That should probably be a new issue.
