> Can you please explain to me how the REPL involves phase-shifting

If you have an entire program text available at once, you can have one pass
through it doing all macro transformations, and then another pass doing the
actual semantics, like the K&R C compiler.

If you have a REPL, every time the user types anything, some semantic work
has already happened, but now you have to do macro transformation before
going back to semantics.
