From within Perl, you can access any Exim variable by calling back to
Exim's "expand" function.

Fetching variables back is not possible.

I'm afraid I do not like this patch, because it is so special-purpose
(it handles only the $acl_ variables). If passing back variables from
Perl to Exim is really a facility that many people want, then some
general-purpose mechanism should be invented, such as a function that
can be called from Perl to take a value and put it in a named variable.
