I don't see the point of using [] at all for repetition :)

This solution is very clear...

And this solution is also clear (e.g., it's close to extended regular 
expression syntax), but ()'s are used for both iteration and grouping. This 
strikes me as being fine (whitespace should be used to make it obvious). 

At this point, there are bigger fish to fry...
