I'm surprised. The Original Poster specified [quote] What python needs is something like a built-in "operator.identity" function, which acts like "lambda x:x", but which the byte compiler could recognize and completely optimize away so there is no function call overhead. [end quote] I would have guessed that optimizing the call away would require support from the compiler. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
