Scenario: I want to determine if My::Module is installed on the current system, so I can have conditional behavior based on whether it is there or not. This is not a strict dependency, so I don't want the standard behavior of "use My::Module". So far I've come up with this: 
if (defined eval "require My::Module") {
    print "all's well\n";
} else {
    print "nope, figure out a workaround\n";
}

But is this likely to be too harsh? There are other conditions that could cause require to fail besides "Can't locate My/Module.pm in xxx".

Suggestions appreciated,

-Jason
