OK, so which is it? Does an assignment statement preceding a special builtin in a shell function create a local variable (as we discussed just yesterday)
Huh? That was about 'typeset'/'declare'. How is that relevant here?
or does it create a global variable because `Posix'?
Yes. POSIX does not specify local variables at all, and even in a bash context I see nothing there to indicate that it should be local.
The possibility that 'foo=bar :' might create a variable 'foo' that survives the ':' command, is exported, *and* is local to the function, hadn't occurred to me at all. POSIX is pretty strange sometimes but not *this* strange.
