Object pointers become nil when the object has been destroyed.

Also, for reference, here is how you try out a simple multiple-line
LPC program in the kernel library (which you have created in advance):

    > compile /dummy.c
    $0 = </dummy>
    > clone $0
    $1 = </dummy#123>
    > destruct $1
    > code $1
    $2 = nil

The probable reason this didn't work for you is that the kernel lib
requires you to compile something before it can be cloned.
