Granted.

The 'echo $FOO' was just an EXAMPLE to reproduce the problem! Think of a
more complicated way someone builds the variable FOO and doesn't want to
put it all on one line. BTW if the second workaround you suggest works,
then it is a bug. The manpage states clearly, that a local variable is
still exported if the ALLEXPORT option is set and the variable was
prviously unset.
