So far, ASDF2, after ASDF, has some kind of determinism in its behaviour.
If you load the same source in the same order from the same image,
you should always have the same result.
Adding user-controlled randomization might be fine,
but it's just not on my TODO list.

Actually, my TODO list for ASDF is: make a last release 2.20 this year,
and try to touch it as little as possible.
I do have projects for XCVB, though, and I encourage you to join me
in my efforts with XCVB if you're interested in a better build system for CL.

Lambda calculus:

Casual call dumb,
A bad CACM lull us,
Ada club all scum.

Abacus clad mull,
Lab calculus mad.
A Dacca bull slum?

Bald caucus mall
Balm ad calculus;
Calamus call bud.

MBA calculus lad,
A clad callus bum,
CACM laud as bull.

UCLA all bad scum:
A scald alum club,
A baud clam scull.

Lambda calculus —
Call us a mad club.
