It seems one possible solution may be to use "eval", e.g $ (function g {
typeset x=( typeset -lE x=1 y=2 ) ; print -- "$x" ; } ; eval "typeset
l=$(g)" ; print ${l.x}) # ... but I wish the use of "eval" could be
avoided (at least it copies the returned string twice instead of one
time and 2nd
http://mail.opensolaris.org/pipermail/shell-discuss/2007-June/000993.html
says "eval" should be avoided unless there is no other option (and I'm
not sure whether this is the case...)) ...
