I was convinced by this example (import (rnrs) (for (only (aps list-utils) distinct?) expand)) (display distinct?);; here distinct is available even at runtime even if I imported it at expand time that it was impossible. Since it appears I was mistaken, I am very curious of how do you instantiate a module at expand time only on at runtime only in psyntax systems.
