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...
