interesting!  If i were you i'd not bother with the standard
library but just publish the module and project on PyPI. 
With two other packages already in it si hard to add
a third and making an extension to optparse is probably 
a hassle. 

btw, myself i'd only use it if it also works <3.0. 
A similar idea i had was this, btw:

    @cmdline
    def main(archer=str, boulder=float, magic=42):

which would wrap a parser around the function 
and otherwise work like your example. This can
easily work down to Python2.3.
