Regarding portability we say three things.
* It is supported practically everywhere, and it is even in POSIX,
so let's use it.
* Even this is not in POSIX, it is supported practically
everywhere, and it is too cumbersome to do things without using
it, so let's use it.
* It is not available in some platforms we (collectively) still
care; it is not even in POSIX. Don't use it.
I think "local" falls into the third one.
: bash; ksh
$ v=1
$ f () { local v; v=2; echo f; }
$ f
ksh: local: not found [No such file or directory]
f
$ echo $v
2
$ exit
: bash;
