Perhaps because map is not a looping mechanism in that
you cannot break out of it by satisfying a test or by
using 'last'. Technically, "goto" and "what?" are
not really looping mechanisms either, and "for" and
"foreach" are the same, which leaves only "while" and
"for". Of course, we could add "anonymous" loops (blocks) as
well, which don't have a test but can use last/next/redo. Maybe
we could stretch things a bit and have a fourth entry of
"do/while"... | [reply] |
