It's quite open; every piece of code using oopspec should be prepared to
see names that it doesn't know about, and ignore them.  So feel free to
add new names.  As a guideline, let's stick as far as possible to the
Python name for the method or for the __xxx__ special method name (with
__ removed): 'remove_range' looks like it could be called 'delslice' in

A bientot,
