     3== Resizable Arrays == 
     4 
     5 1. Do any HLL's use Resizable Arrays without extending them to include initialization of unset elements? 
     6 
     7 They were originally included as counterparts to the Fixed Arrays, but extended to support pop, push, shift, unshift and set-integer. However it seems that the lack of initialization is a misplaced optimization that is probably of no use to any HLL, forcing every HLL to override this behaviour.

     11== Resizable Arrays == 
     12 
     13 1. Update all ResizableArrays to perform initialization of unset elements, in particular those that re-appear when an array is shrunk and then re-extended. Assuming of course no HLL's would suffer significantly from this "pessimization".
