rules = [('S', ['NP', 'VP']), ('NP', ['ProperNoun']), ('ProperNoun', ['John', 'Mary']), ('VP', ['V', 'ProperNoun']), ('V', ['likes', 'hates'])]

Should is_pos(('ProperNoun', ['XYZ',]), rules) return True or False as their is no production which leads for 'XYZ' ?

Returns True as 'XYZ' doesn't appear as a LHS symbol in other rules.
