pkgutil.get_data(package, pickled_grammar)
where *pickled_grammar* is computed from *grammar_source* by adding the
Python version and using a ``.pickle`` extension.
However, if *grammar_source* is an extant file, load_grammar(grammar_source)
is called instead. This facilitates using a packaged grammar file when needed
but preserves load_grammar's automatic regeneration behavior when possible.
