No. If you must, you can get rid of the method on it's first invocation
by deleting the glob from the symbol table, but I wouldn't recommend
doing that.

You could alternatively write your own import method, which removes
enable_debug from the symbol list and calls Exporter->export_to_level to
do the actual exporting.
