Arg decoding with a template?

How about exploiting the python parser ?

>>> args="arg1, arg2, arg3='world'"
>>> s='def f(%s): pass' % args
>>> exec(s)
>>> dir(f.func_code)
['co_argcount', 'co_code', 'co_consts', 'co_filename', 'co_firstlineno',
'co_fla
gs', 'co_lnotab', 'co_name', 'co_names', 'co_nlocals', 'co_stacksize',
'co_varna
mes']
>>> print f.func_code.co_argcount
3
>>> print f.func_code.co_varnames
('arg1', 'arg2', 'arg3')
>>> print f.func_defaults
('world',)
