Nb: A limit is consistent with String.prototype.split which has an optional 
limit in the range [0:4294967295] to avoid excessiveness.

(no great insight, but interesting?)

Subject: Array.filter: max number of matches?


I've been wondering for a while if it would be a good idea to add an argument 
to Array.prototype.filter, for a maximum number of matches.  For example, if I 
have a thousand-element array and I only want three matches, it might make 
sense to truncate the search after the third match.

Put another way:  if I want an intersection between two arrays treated as sets, 
and one array has only three members, then once I've found matches for those 
three, it really doesn't make sense to keep iterating.

Thoughts, anyone?
