Michal didn't say the if/case/while would be inside a rescue, so I 
assumed it was just meant as a question about the general case. Yes, 
since if/case/while within a rescue are all contained within the same 
rescue code body, then I would expect retry would work perfectly well.

Outside of 'for', none of the syntactic loops are block/iterator based.
