Oh, really? This seems really unfortunate -- AFAICT it makes it impossible to write a generic broadcasting matrix-solve or vector-solve :-/ (except by explicitly checking shapes and prepending ones by hand, more or less doing the broadcasting manually). Surely it would be better to use PEP 467 style broadcasting, where the only special case is if `b` has exactly 1 dimension? -n -- Nathaniel J.
