Damien George 3558f62fb5 py: Making closures now passes pointer to stack, not a tuple for vars.
Closed over variables are now passed on the stack, instead of creating a
tuple and passing that.  This way memory for the closed over variables
can be allocated within the closure object itself.  See issue #510 for
background.
