How in general can you tell if a module is present or loaded? if
defined(X) what should X be?

I want to disable some features in a big perl script by
conditionalizing the code that relies on those modules and be able to
disable those features by comment out the "use" line for the modules.


Here's one way:

use Data::Dumper;

my @watergate = qw(Haldeman Nixon Colson Dean);

if ($INC{'Data/Dumper.pm'}) {
print Dumper(\@watergate);
}
