I just want to chime in with how static variables can be bad for multi threaded code, yet they aren't considered as bad as global variables. E.g. the find_path guido example will explode if called by 2 threads in tandem. I believe this is more apparent and frowned upon when caused by global variables.
Are you saying that Guido's find_path example is thread-safe when written with the default argument hack, but will fail with the new proposal?
Hasn't python given enough temptations to avoid multithreading already?
One can never have enough reasons to avoid multi-threading! <wink> But seriously, unless this proposal makes things *worse*, I don't see why this is an objection.
Allowing these fast, local, persistent static variables is like allowing braces instead of whitespace - the good coders will manage either way but the bad will do bad things with it.
That's an analogy that makes no sense to me. -- Steven
