two ideoms at one blow: line-reading and regexp-matching

[logistix]

Your ideoms are only clearer if you've been poisoned by C.  Don't worry,
we've all been guilty of that at one point or another.  Too many languages
have been screwed up by trying to maintain some sort of C ideom status quo.

Someone who's never programmed before won't find your proposed syntax clear
at all.
