OK, so I should have that `t'!

But if so, sometimes the b.el and not the b.elc
will be `require'd by a.el->a.elc (whichever is
correct to say does the the requiring - a.el?).

Is there a downside to this, assuming the
latest version is always the better, and b.elc
*is* compiled eventually?

If there is a downside, i.e. it _is_ better to
load the byte-compiled code (assuming it to be
newer than the source), what should one do?
touch(1) a.el and byte-compile again?
Because then, there should be no problem with
b.elc being out of date! If this is correct,
perhaps the byte-compiler should tell what file
has the problem to begin with?

Or even not do anything about it (a.el), and
then one would simply compile twice? Hm, maybe
this can get messy if one have lots to
require... - but as long as they are not
circular it should work out fine, right?
