65b65a2a3e Introduce tests for split-by-first and split-by-completely 
Allows one to split by string delimiter, or anything else.

d357964e2f FINALLY figured out puzzle 10 2022 
Part 2 was a real struggle to get right, though part 1 was way easier.

07a5f754da Update lib.lisp to be more imperative and include a threading macro 
Instead of (f (g (h (j (k x))))) we can write
(-> (k x)
    (j it)
    (h it)
    (g it)
    (f it))

which is works really well for particularly large and complicated
expressions.

e5c805a17a Finished round 2 of puzzle 9 
Annoying bug that took ages to fix: for multi-execute, there may be
times where movements go in complete diagonals.  In this case, we need
to move in the unit vector diagonal direction.  So I modified
update-tail for this case.  Never happens in round 1 lol.

b99cda7087 Finished round 1 of puzzle 9 
Pretty interesting, functional idioms kinda fail here as there are no
nice functions I can think of for the single-knot-execute-line
`dotimes` section.  I could use tail recursion with an optimisation
but this is pretty explicit.  You can compare execute-lines to
execute-line to see which type of iteration fits you.

Does what they say, all is the logical inverse to some.

f11415c365 FINALLY figured out the solution to puzzle 7 
Easy problem once I figured out the trick to constructing an
inherently stateful structure with backwards pointer references (at
least the first way I would've made it) into a functional alist
solution.  Very cool.

Not complete, dunno what to do for parsing and handling CD commands.
