Yes, no problem. You can also use a variable in the whole process. For example if you need to load a series of modules,
my %objects;
for my $class (@available_classes) {
eval qq(require $class);
if ($@) { # you can make it die() here, if you want
warn "Failed to load class '$class': $@";
next;
}
$objects{$class} = $class->new;
}
Because the way
require works, you have to eval the
require $class statement in double quotes so the
$class becomes bareword.
Or, you may have to pick a correct class by certain criteria. You can use UNIVERSAL::require in place of the eval statement and $@ checking.
use UNIVERSAL::require;
my $class = get_implementor_class(); #defined somewhere
$class->use or die $@;
my $object = $class->new;
