Anyone have the historical context of why Traversable#filter is not defined in terms of CBF (w/out getting derailed by the pains of CBF)?
@chrslws If I *had* to guess, I'd think it is because filter returns the same type, where as map may not (eg. String#filter vs String#map)

@chrslws That would be my guess as to the historical reason, anyways. Since I remember a lot of String and BitSet examples back in the day. -
@tixxit Yeah that could explain it. Seems unsound that map might return a different kind though ... - 2 more replies
