The key, of course, being that you have to explicitly take the reference to the variable in the use line (and never dereference it in the module until you're actually using it).

Nah, the explicit reference is too evil. Besides, I'm going for transaction $dbh, sub { ... }; instead.

Juerd # { site => 'juerd.nl', plp_site => 'plp.juerd.nl', do_not_use => 'spamtrap' }
