The generators are initialized with NULL pointers for underlying
expressions.

<DD>Fill the index of the array with the generator. Assumes
<CODE>array->env==gen->env</CODE>. Nothing is duplicated. The argument should
never be cleared. (its environment is dereferenced). If a generator
was already stored, it is first cleared. Return true iff problem
