in reply to use module if condition is met

use if $type eq 'x', Some::Module;

[download]

Of course, that requires the value of $type to be known at compile time. Otherwise, do something like: 

if ($type eq 'x') {
    require Some::Module;
    Some::Module -> import if Some::Module -> can ("import");
}
