Oracle does use USING:

EXECUTE IMMEDIATE dynamic_string
[INTO {define_variable[, define_variable]... | record}]
[USING [IN | OUT | IN OUT] bind_argument
[, [IN | OUT | IN OUT] bind_argument]...]
[{RETURNING | RETURN} INTO bind_argument[, bind_argument]...];

so I think we are OK there.

The only case I see you using it is for \:. What is the purpose of
that? Can't we use :: for a literal :?

I have attached the patch from March.
