You would also have to import the KW constructor function before you
can use it.

  use Python qw(KW);

which tilts it in the direction of _too_ ugly in my taste.


Another silly(?) idea. We could misuse globs, as I can't see a reason
why you would want to pass them to a python function otherwise:

   $obj->foo($pos1, $pos2, *key1 => $val1, *key2 => $val2);

This is kind of similar to :keyword symbols used in Lisp.  One
downside is that these symbols seems to stick forever in the symbol
table after use.
