no the error is in class_addmethod(): pd does not allow to have messages
of with arguments "<float> <symbol>" automatically typechecked (the
reverse "<symbol> <float>" works fine).
i have changed that to use A_GIMME but have forgotten to check it
in...should be fixed now.
it should appear in the anonymous CVS soon (in the meantime, just
download it from the webCVS interface)
