if method_name not in self._scrubbed_method_names:<EOL><INDENT>self._scrubbed_method_names[method_name] = (<EOL>scrub_method_name(method_name))<EOL><DEDENT>return self._scrubbed_method_names[method_name]<EOL>
Scrubs a method name, returning result from local cache if available.

        This method wraps fitparse.utils.scrub_method_name and memoizes results,
        as scrubbing a method name is expensive.

        Args:
            method_name: Method name to scrub.

        Returns:
            Scrubbed method name.
