Okay... ;-)

however, my connection of "dbmopen" with "DB_File" is straight out of the 1st Perl Cookbook, but "tie" from the DB_File man doesn't seem much different, nb. they both produce

Global symbol "%email" requires explicit package name at /usr/local/bin/AddressBook line 6.

even with
tie %email, "DB_File", 'email.db';

as long as use warnings/use strict is enabled (otherwise it's fine).

"use strict;" means that variables should be declared, so

tie my %email, "DB_File", 'email.db';
--------^^

To anyone's knowledge is there somewhere/one who has connected these strict warning messages to specific meanings in context? (they would seem very useful if that is the case, otherwise i cannot imagine what "requires explicit package name" could mean beyond the supplied "DB_File")

Literally it suggests this:

tie %main::email, "DB_File", 'email.db';
---------^^^^^^
It's not the best worded error message in Perl...
