No, it is not standard POSIX (yet). There has been talk on the Austin
Group mailing list of standardizing local (perhaps by the name typeset)
for the next revision; the biggest issue is that ksh uses typeset only
for statically scoped variables, while bash uses it only for dynamically
scoped variables, so a consensus has to be reached among shell writers
which scoping rules to standardize.
