modpods - print out paths for the standard modules
DESCRIPTION
This program outputs the paths to all installed modules on your systems.
This includes both the standard modules (which the stdpods command
produces) and the site-specific ones (which the sitepods command
produces).
This is just a front-end for calling pminst -l, supplied
to make it more obvious what it does.
EXAMPLE
This finds all the modules whose documentation mentions
destructors, and cats it out at you.
Having read L<perltie> you will probably have already guessed that the
error is caused by the extra copy of the tied object stored in C<$X>.
If you haven't, then the problem boils down to the fact that the
B<DB_File> destructor, DESTROY, will not be called until I<all>
references to the tied object are destroyed. Both the tied variable,
C<%x>, and C<$X> above hold a reference to the object. The call to
untie() will destroy the first, but C<$X> still holds a valid
reference, so the destructor will not get called and the database file
F<tst.fil> will remain open. The fact that Berkeley DB then reports the
attempt to open a database that is alreday open via the catch-all
"Invalid argument" doesn't help.
