=== *Description* ============================================================
Creating a compound variable in s subshell "bleeds through" to the calling
subshell in some conditions.
Example:
-- snip --
$ ksh93 -c 'unset l ; ( l=( a=1 b="BE" ) ; print "$l" ) ; print $l'
(
a=1
b=BE
)
( )
-- snip --
The first bracket pair is Ok since it's coming from $ print "$l" # , however
the 2nd pair comes from the print $l _outside_ the subshell where the variable
"l" should no longer exist.
Workaround:
Force ksh93 to call |fork()| for the matching subshell using $ ulimit -c #,
e.g. ...
-- snip --
$ ksh93 -c 'unset l ; ( ulimit -c 0 ; l=( a=1 b="BE" ) ; print "$l" ) ; print
$l'
(
a=1
b=BE
)
-- snip --
... provides the correct output.

=== *Workaround* =============================================================
