heh, fair enough! :) i wasn't even expecting you to look.

i'm also rather happy with Nix(OS). i already started putting together
a default.nix file for clasp, and i'll play with it more tomorrow.

(it encodes all the necessary external dependencies, and automates
setting up an environment with them on any linux where Nix is
installed. perfect for CI jobs, too.)

i'm sure parts of UIOP would be useful. i'm not sure i'd get the
complexity of ASDF on my shoulders; much of it seems to be due to
legacy cruft.

no, it's already helpful, thank you!
