I beleive in Perl 6 the repeat applied to a capture group will cause that number to be an array. Or you can explicitly name it with an array name. Something like that.

I don't see why you shouldn't be able to capture separatly in principle, if there is a fixed upper number. But Perl 5 regex syntax doesn't support that. You could squish the redundancy by making the repeat stuff in a variable and interpolating it n times or with a x operator. That would give you the "in one place" nice thing for maintainability.
