Quantified subpatterns

• Quantified subpatterns always result in an array of Match objects

regex statement_list { <statement>* }

• $/<statement> becomes an array of Match objects
• $/<statement>[0] is the Match object of the first statement
• $/<statement>[1] is the Match object of the second statement
• etc.

• The same is true if a subrule appears more than once in an alternation

regex number_list { <number> [ ',' <number> ]* }

• Note that the ? quantifier also produces an array (of 0 or 1 matches)
