Well, :REQUIRE triggers the generation of a REQUIRE-SYSTEM only if the
implementation doesn't provide the module via a regular system (as
SBCL used to do). Then, the actual loading is done by the
corresponding PERFORM method, which calls CL:REQUIRE. To make what you
say more ambiguous, the PERFORM may be the result of an OPERATE
'LOAD-OP that is itself a product of calling REQUIRE, and some of the
complexity is due to prevent circularity.
