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

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