That is true, but seems a joke... :)

OK.

In this case you should `defvar' them (to make them known to the
byte-compiler), and then `defconst' them to make unmodifiable. If
there were ever to exist true constants in Emacs (which I see Richard
is vetoing), the ability to switch the constness state would be
necessary.

The only answer to this would be to make sure constants have
significant, hard-to-repeat-by-accident names. Instead of `e', that
should be `number-e' or `*number-e*' or `transcendent-constant-e' or
whatever.

That seems correct.
