-;; The array module specified by slib 3a1 is not the same as what guile
-;; provides, so we must remove `array' from the features list.
-;;
-;; The main difference is `create-array' which is similar to
-;; `make-uniform-array', but the `Ac64' etc prototype procedures incorporate
-;; an initial fill element into the prototype.
-;;
-;; Believe the array-for-each module will need to be taken from slib when
-;; the array module is taken from there, since what the array module creates
-;; won't be understood by the guile functions.  So remove `array-for-each'
-;; from the features list too.
-;;
-;; Also, slib 3a1 array-for-each specifies an `array-map' which is not in
-;; guile (but could be implemented quite easily).
-;;
-;; ENHANCE-ME: It'd be nice to implement what's necessary, since the guile
-;; functions should be more efficient than the implementation in slib.
-;;
-;; FIXME: Since the *features* variable is shared by slib and the guile
-;; core, removing these feature symbols has the unhappy effect of making it
-;; look like they aren't in the core either.  Let's assume that arrays have
-;; been present unconditionally long enough that no guile-specific code will
-;; bother to test.  An alternative would be to make a new separate
-;; *features* variable which the slib stuff operated on, leaving the core
-;; mechanism alone.  That might be a good thing anyway.

-;;; loaded when something accidentally appears in the path before
-;;; slib, etc. ad nauseum.  However, the right fix seems to involve
-;;; changing catalog:get in slib/require.scm, and I don't expect
-;;; Aubrey will integrate such a change.  So I'm just going to punt
