By the way, I just thought that for real programming, I would love to have a -Wcrossplatform command switch, which would warn for all unportable constructs in one go. That way, I don't have to remember which parts of 'os' wrap posix-only functionnality.
When I developed using PHP, error_reporting(E_ALL) was really useful. I would like a same function on Python, but I realized that it is not necessary. Python is already strict *by default*. Python can help developers to warn them about some "corner cases". We have already the -bb option for bytes/str warnings (in Python 3), -Werror to convert warnings to exceptions, and ResourceWarning (since Python 3.2) for unclosed files/sockets. I "just" would like a new warning for an implicit locale encoding, so -Wcrossplatform would be as easy as -Werror. -Werror is like Perl "use strict;" or PHP error_reporting(E_ALL). Use -Wd if you prefer to display warnings instead of raising exceptions. See issue #11455 and #11470 for a new "CompatibilityWarning", it's not "cross platform" but "cross Python" :-) It warns about implementation details like non strings keys in a type dict. Victor
