As I said, it doesn't belong there. If you want to have it in the dynamic
you should only invoke it after execution.
I think you should use VarInfo* lookup_var(const store::Item* qname) const;
VarInfo contains the type of the variable.

Double check with Sorin whether he really doesn't need the occurrence indicator
