handle all dispatching for colon operator in do_colon_op function * ov.cc (do_colon_op): Handle all dispatching here, but using lookup based on argument vector passed to feval instead of determining dispatch type separately. * pt-colon.cc (tree_colon_expression::evaluate): Simply evaluate arguments and pass them to do_colon_op. * test/colon-op: New test directory. * test/module.mk: Update.
