Ah yes, that's it: the 'x if b else y' syntax wasn't introduced until Python 2.5; see http://docs.python.org/dev/whatsnew/2.5.html#pep-308-conditional-expressions for more. Hmm. Maybe we shouldn't be using this syntax in from_float, if it's the only thing that prevents the trunk version of decimal.py from being used with Python 2.4. On the other hand, from_float isn't going to work until 2.7 anyway, since it uses a whole bunch of new stuff: as_integer_ratio and copysign (both introduced in 2.6), and bit_length (introduced in 2.7).
