This is true of many good programs.
On the other hand, many programs are not good programs. And it
winds up being true of many bad programs too. :-)

I'm not so sure: I learned some of this myself when working on my
Z80 assembler written in (some Microsoft variant of) BASIC.
Because it was such a terrible language, I had to keep a master
"notes" table giving each subroutine's line numbers, input
variables, and output variables (no call-by-anything in BASIC so I
had to stuff a register name like "BC" "DE" "HL" "IX" "IY" into
one global variable, "GOSUB 10100", and take the result back in
more global variables).
Nonetheless, it's true that seeing / recognizing "good" vs "bad"
software is a valuable pattern matching skill. As with all such
things, the best trick I've ever discovered is not just to learn
from my own mistakes, but to learn from *other people*'s mistakes
