paul j3 added the comment: I should probably give PR 120 more credit. By checking the group's container it in effect eliminates this overlapping action problem. Nested groups aren't used in the usage, just the union xor.
Maybe the question is, which is better for the user? To tell them up front that nesting is not allowed, or to display the union group without further comment? Does allowing nesting on the input give them a false sense of control? More often on StackOverFlow users try to nest ArgumentGroups in a mutually exclusive one, thinking that this will give some sort of 'any-of' logic. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29553> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
