Maybe something like special variables, e.g. $1, $2, ... instead?

That would remove the need to check the type, but reduce readability,

Personally, I prefer to be able to give specific names other than
"key", "value", "item", like "person", "date", "sex", etc.

Might be useful for more generic code, OTOH.
