This will not help=2E The keys are changed when they are *written* to the =
array, not when they are read back out=2E No option to array_keys can tell =
you whether the key 42 was originally set as '42', because that information=
 is not stored anywhere=2E

Yes, I think this was suggested a couple of times on the previous thread=
=2E It would be a useful feature, but probably not easy to implement effici=
ently and integrate thoroughly into the language=2E
