Yes, anyone who tries it will realize this immediately. :-)

You don't need the export.
% FOO=whatever /bin/echo $FOO
whatever
$FOO goes in the child's environment, but not the parent's. And
since environment variables aren't shell-specific (like the OP's
aliases) you can also set them from Perl.
$ENV{FOO} = 'whatever';
system qw(echo $FOO);

No kidding... Sometimes the list form of system() makes this easier,
and non-interpolating quotes always help.
system qw(ksh -c), 'TEST=hello; echo $test';
