Various "bashrc" & and "profile" files refer to "aliases and functions".
That should instead be "aliases, non-exported functions, and
non-exported variables".

I could go on about the poor shell startup-script scheme (BASH_ENV,
/etc/profile.d, etc.), but I suppose it's a feature, not a bug.
Much of the fault belongs to bash.  They must have worked hard to
make something so simple so confusing, namely to control what
happens at the startup of four combinations of (non-)interactive
and (non-)login shells.  I've got a small "profile" which sets
a couple of variables for "bashrc" and everything else is there
in "exported" and "not exported" sections.
