The "sections of code" are shell functions, essentially shell scripts
pre-read by the shell (usually from .profile or various equivalents
thereof) to speed them up.  This is the right way to do "aliases" -- the
separate alias mechanism in bash is basically for backward compatibility
with historical mistakes.

They're sort-of-kind-of variables containing shell code rather than text
values, which is why they show up in "set" output.
