Weak points in the current Erlang implementation/libraries:

* Algorithms that involve destructively updating arrays.  You can
mimic this with a hash (in the guise of an ets table), but it's not
* Unicode strings.
* Regular expression matching (there's a module, but watch Perl beat
it by a factor of 100).
