Fellow monks,

for some module, I need to include other modules based on run-time information. Here's roughly what I am doing right now:

    sub init {
        my ($someModule, $someCondition) = @_;

        eval "use Acme::$someModule";
        eval "use Funky::Library"
            if $someCondition;
    }

    init("Bleach", 1);

Now, for some reason, I don't really like eval "$some $code". I fear the performance hit (although I have no idea whether there really is one), and more importantly I just don't like the thought of compiling during runtime. I guess I could rewrite the code using require and import, like this:

    sub init {
        my ($someModule, $someCondition) = @_;

        require "Acme/$someModule.pm";
        import "Acme/$someModule.pm";

        if $someCondition {
            require Funky::Library;
            import Funky::Library qw(grooves moves);
        }
    }

    init("Bleach", 1);

Is this the canonical way to solve that problem; are there any issues I need to be aware of?
