Ever since I started using ASDF I have been mildly bugged by redundant
recompilations: recompilations of fasls that are already up to date.
This problem doesn't seem to have gone away: I was just trying the new
ABCL (with ASDF 1.719) to see if it could run FSet, and every time I
restart ABCL and load FSet, ASDF recompiles several files, despite the
sources not having changed.

I'll put together a proper bug report for the maintainers, but first
I'm curious, because I haven't heard anyone else complain about this:
does anyone else see this behavior?

Not nearly as bad as you describe; but yes, I have seen what appear to
be spurious recompilations. I have seen some files which always
seemed to recompile. Never tracked down the details. Suspected the
fasl wasn't being written properly due to a spurious warning or the like.

Regardless, I have a fundamental issue with merging the functionality
of "make" with "load and execute". It is nice that they can be
coordinated, but wrong to think tight coupling should be the default.

I'm not sure I follow. Are you suggesting that ASDF, when asked to
load a system, should refuse to do so if it has not already been
compiled?

That is one implication of my statement. While there are many things
to mock in the land of C, a "dumb" workflow can have advantages.

In particular, the classic "configure && make && make install"
sequence provides several useful hooks for the end-user to check that
things are working properly. Did configure find the right stuff? Did
make succeed? Am I ready to install to the default places used by
other programs? ...

Defsystems like ASDF seem to discourage anything but a single-hacker,
single-project mentality. In my experience, the C model allows
finer-grain mixing of libraries since I don't have to worry about
things changing underneath me. Its dumbness approaches the smart
immutability preached by Clojure.

That said, I see no need to perpetuate the GNU toolchain of autoconf,
automake, shell, make, cpp, cc, linker, loader, ... We can do
everything in one monolithic lisp; we just need to make the pieces
accessible individually as needed.

Later,
Daniel

P.S. Hope I'm not incoherent. Its very late now...

Isn't that a fundamental issue of Common Lisp?
