493a3a6312 (mev) call expand_value only at the end 
There is no need to expand array values throughout evaluation.
They are expanded during array equality checking (if requested), and
can be expanded at the very end of evaluation (if needed).

d5ca902bf6 (mev) bug fix in expanding array equalities

  (store a x u)
