Now, if you must, how 'bout this:
"""
def make_enum(func, base):
    g = globals()
    for i in range(func.func_code.co_argcount):
        g[func.func_code.co_varnames[i]] = i+base
    del g[func.__name__]
# after this, you can fake an enum like this
def enum(ONE, TWO, THREE) : pass
# and you activate it so:
make_enum(enum, 1)
# here we are:
print ONE, TWO, THREE
#(1, 2, 3)

I think I have to duck and cover if Timbot watches me :-)
