The return type is listed as int, but all the examples show the return type being tested as boolean.
Before thinking it through I wondered if it might return the number of pattern elements matched. My
quick test returned the value 1 from an successful match on six pattern elements. Although you
could construct a pattern where the the match succeeds with a variable number of subexpressions
matched by marking entire subexpressions as optional, it doesn't make sense to think of it this
way.
Are there any other possible return codes aside from 0 or 1?
