/me blinks.
What does that have to do with anything? IIUC, the question isn't
whether CONCAT() would work for large arrays, but rather for very
large numbers of arrays written out as CONCAT(a1, ..., a10000000).
I don't understand why an appropriately-placed check against
FUNC_MAX_ARGS does anything other than enforce a limit we already
have. Or are we currently not consistently enforcing that limit?
