I'm not sure it's the right term for what's happening here,
though. Nothing is being lifted to a higher level -- the
functions remain at the same level they were written at.

It's more that Pascal is designed to make single-pass
compilation easy. It's possible to support out-of-order
declarations with compile-time type checking using two
passes; Pyrex does this, for example.
