            Alternative operands are tried one by one on a first-match-wins basis
            starting from the leftmost operand. After a successfully matched alternative
            is found, the parser concludes its search, essentially short-circuiting
            the search for other potentially viable candidates. This short-circuiting
            implicitly gives the highest priority to the leftmost alternative.
