    # interpolate!
    s = I('Joe has $ ', a, ' in his pocket.')

or perhaps

    # print-like interpolation
    s = P('Joe has $', a, 'in his pocket.')

works pretty well too.  in all versions of python, with all existing
syntax-aware tools.  and if written in C, it's probably as fast as
any other solution...

(implementing I/P is left as an exercise etc etc)
