Yes, although I don't understand why you'd want to so dramatically
move away from SRFI 7 when it is such a trivial amendment to SRFI 7,
SRFI 7 provides much more quite useful functionality anyway, and SRFI 7
permits extension considerably more easily: the PROGRAM form is a quite
general form, whereas REQUIRE-EXTENSION has only one purpose, to
declare a dependency on a feature.
