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? -- "The first step in confirming there is a bug in someone else's work is confirming there are no bugs in your own." -- Alexander J. Vincent, June 30, 2001
