Well, I think foo3 is, but yeah, I know what you mean.

I do. Actually I posted this by mistake to the phpunit mailing list

Yeah. There are static checkers out there, even some FOSS ones. I guess
I'm just a bit frustrated that (as you say) the man page says that "-l"
checks syntax but doesn't really detail what kind of things that
covers. Actually, I can't even find a decent description of what
E_STRICT covers :( just that "Enabling E_STRICT during development has
some benefits. STRICT messages will help you to use the latest and
greatest suggested method of coding, for example warn you about using
"Some benefits"? "For example"? Telling people exactly what is covered
seems more useful, to me. Meh. Anyway, that's my whine over for the day
