What language are we speaking of here?  I'm sure somebody here would be
interested in a description of this mystery construct, if it's sufficiently
elegant. Sorry, I find your post amusingly cryptic.

It should be mentioned that map and filter (and especially their buddy
lambda) are lonely immigrants from the land of functional programming, and
are regarded with suspicion by many of the natives.
