Description

I was surprised at this -- obviously we haven't used insert much ;-)

/**/ L := [];
/**/ insert(ref L, 1, "a");
--> ERROR: Cannot index an empty list
--> insert(ref L, 1, "a");
-->               ^

when seems pretty reasonable to expect get L = ["a"].
In general: insert does not work at the end of the LIST.

The function actually implementing this calls insertValue which calls insert (in Interpreter.C).
So I just had to add checkIndexOrEnd which is a slightly modified copy of checkIndex allowing an extra position after the end.
