Category talk:Operas set in mythological places

Definition?
This is one of the longest cats I have ever seen. Is it really useful? IMO it either should be rigorously defined or sent to Cfd. Any opinions? -- Klein zach  00:33, 1 March 2011 (UTC)
 * Some time ago, a harmless-looking Category:Operas by setting appeared. Sub-cats were "Operas set in [country]".  This category was a useful mopping-up one devised for operas not set in any country.  It was rigorously designed for that purpose, and I can't see what you've got against it, apart from the trivial matter of its name.  As often happens, various other anomalous categories seem to have sprung up here since I last looked, but back then everything was in order. --GuillaumeTell 01:39, 1 March 2011 (UTC)
