Random numbers Perl ok! (I think)
Something not conceptually right. The entity suffers from this problem (if that article you mentioned is right) is: the algorithm that used to generate random numbers, not the language.
The laguage is only loosely related to this problem, as whether you picked a good algorithm. Impletation is also not related here, as you may have a bad implementation that suffers from performance issues, but an implementation (if it truely follows the algorithm) does not usually alter the characteristic of the algorithm. Especially for something like generating random numbers, the implementation most likely already have been refined again and again...
From Perl's point of view, it makes sense for perl to call c function to do this kind of stuff, but not doing it itself. That's not what Perl is targeted for.
