Pascal, it looks like either x is not an object or the subscripted 
assignment is called from inside a class method. In these cases x is 
considered a struct array and x.types creates a cs-list, which cannot be 
indexed.

Please verify with typeinfo (x) that x is of type “class”. Is the code 
located inside a class method?
