This piece of code is stolen (and paraphrased) from DB2::db: 

        # [...] Rather than using
        # eval STR to eval "require $[...]pm", we do it ourselves.  Th
+is
        # is slightly faster (Benchmark shows about 20% faster).
            (my $pm = $type) =~ s.::./.g;
            $pm .= '.pm';
            eval { require $pm };

In short - I hate eval STR. Anything to avoid it. If I can't avoid it, I'll abuse the heck out of it, but when I can avoid it, I do.

When I noticed Corion talk about UNIVERSAL::require, I was tempted to send in a patch similar to the above. I changed my mind solely because I decided against using that module. Neat idea, but my gut tells me it's just not clean (polluting UNIVERSAL, that is, not having a user-friendly, aka string-friendly, require).

That, and I haven't really gone through the effort of rigorously testing it. :-)
