Wait until Python 3.4 or 3.5 (or Python 4000?) when functools.wraps automatically preserves the function signature? Alas, I think this is a hard problem to solve with current Python. You might like to compare your solution with that of Michele Simionato's "decorator" module: http://micheles.googlecode.com/hg/decorator/documentation.html See this for some other ideas: http://numericalrecipes.wordpress.com/2009/05/25/signature-preserving- function-decorators/ Good luck! -- Steven -- http://mail.python.org/mailman/listinfo/python-list
