It's not an escape for ".", it's a general escape. Most escape systems work that way so that you can escape anything if you are unsure what chars it's needed for.

what has not been asked yet is:
why is there an escape for .? they are not special characters in strings.
for a moment i thought this could be to help simplify arguments to regexps, but that can't be as the escape will be replaced before the regexp handler sees it.
so when was . introduced and to what end?
