floor(Inf) and floor(NaN) do not appear to be defined in Standard Haskell.
(They both come down to "properFraction" which is only defined for Ratio.)
This differs from (for example) the Standard ML Basis Library, where it
is specified that floor(Int) should raise Overflow and floor(NaN) should
At the time of writing, I am waiting for yet another long Haskell re-make of
lots of modules to complete. The frustrating thing is, that at least 90% of
these
remakes are actually completely unnecessary.
I'm afraid I've not gone through your detailed suggestions, but in the
short term,
Suppose that B had imported C only
to export it again (either by listing it in the export list, or not
having any export list at all).
Wrong. If B imports C and has no export list, nothing from C is
re-exported, only definitions from B itself, with the single exception
of C's instance decls.

This scheme is not the cleverest that could be devised. For example it is
still necessary to recompile whole chains of modules if you add an import
declaration. (Not to a system library, imports from those are counted as
"stable" in GHCs and my system.) To fix this

OK, but this has no influence at all on my suggestions except to make
them work slightly better.

No, fraid not. GHC already does this hack anyway. Algol68C didn't have
interface declarations. Still, nice to find someone else

No I'm not. What about documenting it somewhere?

Then you recompile C. You will find that C.hi now has a new version

I take that back. I AM using it in the big program I mentioned, but I still
get huge swathes of unnecessary compilations. Maybe it needs to be still

I think that's a fine suggestion which GHC HQ will probably
do something about (Section 3.7.4 doesn't actually mention
it by name.)
