ah, that's just what I was hoping for...
in the meantime, here's my quick and dirty:


import csv

def fakeparse(s):

    print "======="
    argl=[]
    ix=s.find('(')
    if ix == -1:
        func=s
        argl=[]
    else:
        func=s[0:ix]
        argstr=s[ix+1:]
        argstr=argstr[:argstr.rfind(')')]
        print argstr
        for argl in csv.reader([argstr], quotechar="'"):
            pass

    print s
    print func
    print argl

    return func,argl


print fakeparse("junkpkg.f1")
print fakeparse("junkpkg.f1()")
print fakeparse("junkpkg.f1('aaa')")
print fakeparse("junkpkg.f1('aaa','bbb')")
print fakeparse("junkpkg.f1('aaa','bbb','ccc')")
print fakeparse("junkpkg.f1('aaa','xx,yy')")
