The ' (prime) names are mnemonic for "primitive type" math. That doesn't work if you reverse the meanings. In that case the names would be better with something like do + - * / ++ -- (or maybe 1+ 1- or +1 -1 though that requires tweaking the definition of symbol) for primitive math and loop add sub mul div inc dec for boxed math. -- Sent from my Android phone with K-9 Mail.
