Status: New Owner: ---- Labels: Type-Defect Priority-Medium New issue 1645 by jorn.baayen: [PATCH] Can not expand or simplify piecewise functions http://code.google.com/p/sympy/issues/detail?id=1645
The problem is that the Piecewise constructor does not accept args of type ExprCondPair (although it stores its args as such internally). I attach a fix. Another problem with Piecewise functions is that Basic.__contains__ does not work because bool.__contains__ is not implemented (the condition part of an expression-condition pair can be a simple truth value). The attached patch also sympifies 'bool', but I'm not sure if this is the right thing to do -- it does however fix the problem.
