Ok, didn't take me an hour.  Done.  Check it out.

    [andersen at slag busybox]$ ./busybox sh

    hush -- the humble shell v0.01 (testing)

    /home/andersen/CVS/busybox $ env | grep FOO
    /home/andersen/CVS/busybox $ FOO=bar
    /home/andersen/CVS/busybox $ env | grep FOO
    /home/andersen/CVS/busybox $ echo $FOO
    bar
    /home/andersen/CVS/busybox $ export FOO=baz
    /home/andersen/CVS/busybox $ env | grep FOO
    FOO=baz
    /home/andersen/CVS/busybox $ echo $FOO
    bar
    /home/andersen/CVS/busybox $
