I can't think of an application where the current behaviour would be of great benefit. It's always possible to create a tuple of the fields you want in the comparison. Unless it caused a drop in performance, I'd be in favour of only having identity comparison for code objects.
Well, then perhaps code object comparison (and function object comparison) ought to work the same as 'is', not try to do something clever? This would be ironic since that's what it *used* to do long ago, and then I thought it would be "better" if "equivalent" code objects compared equal. It seems that there are no real use cases for having a code object equivalence test, so we might as well save the effort. Right?
+1 I can't guess why someone would want to compare code objects for something other than object identity. If someone has a specific use case, there is enough introspection available that they can compare the bytecodes, constants, &c and produce whatever result they want. Jeremy
