Is there a reason to reuse $address_data? It seems unwise.
Folks passing data down using $address_data, letting content be
${extract}ed from it, may well want to log/process data from that, but
also have something else be passed in as the ACL argument. Eg,
${extract{usercode}{$address_data}} for log-purposes, showing that
delivery was done by authenticating as that usercode.
If there's no specific reason to override $address_data, just add a new
variable.
If the ACL returns non-accept, does that cause an immediate expansion
failure? Does it count as a forced failure?
