Including renaming (I want to know if you support the renamings at all, if I should make them more of an idea to be considered when we get closer to Python 3.0, or just drop them) and the new exceptions? > Goal: keep bare "except:" but > change it to catch only the part of the hierarchy rooted at > StandardError. > Why the change of heart?

So just ditch StandardError, which is fine by me, or go with Nick's v2 proposal and have all pre-existing exceptions inherit from it? I assume the latter since you said you wanted bare 'except' clauses to catch StandardError. > - Make Warning a subclass of Exception. > > I'd want the latter point even if the rest of this idea is rejected; > when a Warning is raised (as opposed to just printing a message or > being suppressed altogether) it should be treated just like any other > normal exception, i.e. StandardError. > Since warnings only become raised if the warnings filter lists it as an error I can see how this is a reasonable suggestion. And if bare 'except' clauses catch StandardError and not Exception they will still propagate to the top unless people explicitly catch Exception or lower which seems fair. -Brett _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
