Nick Coghlan <ncogh...@gmail.com> added the comment: I'm not comfortable adding a dependency on inspect to the contextlib module, and I think it would be undesirable to have too many cases where the early validation is silently skipped.
While I like the idea of adding early signature validation to these APIs in principle, given the above concerns and the fact this probably crosses the line into "feature" territory, I think we want to wait until 3.4 and the introduction of a mechanism that adds introspection support to callables implemented in C. That will likely involve moving the signature support somewhere lower in the module stack (perhaps to a private "_signature" module, with inspect remaining the official API), and will reduce the number of cases where pre-validation is skipped. ---------- versions: +Python 3.4 -Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15185> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
