Last refinement: To make an import of enum
possible, I have to obtain the globals from the lambda:
"""
# in somewhere.py
def enum(func):
    g = func.func_globals ; code = func.func_code
    base = apply(func, (0,)*code.co_argcount) or 0
    for i in range(code.co_argcount):
        g[code.co_varnames[i]] = i+base
# Now I can do
# from somewhere import enum
enum(lambda ONE, TWO, THREE, FOUR, FIVE:1)
# added by PSST:
print ONE, TWO, THREE, FOUR, FIVE
