"but all objects respond to value..."; thx, Santiago -- that makes more
sense, that or: cares only about its receiver/argument evaluable as a
Boolean, no matter they started as blocks, expressions, or something else
(makes me wonder if a bare-value is a degenerate case of a block ... but
don't mind me, I'm just talking aloud). separately, point taken re
expressions being evaluated, and blocks possibly not.
