I use a Python method as a callback given to <block>.set_msg_handler. This is certainly called when I use the message strobe to input a message to the block, but not when using _post. Is this some new feature? Or am I wrong that the operation is the same?

Well SWIG not supporting it (see [1]) doesn't mean one can't write
custom code to run Python from the C end. Python blocks are implemented
via a gateway [2] to do this.
