Not a terribly new paper, but things are slow and I don't think we've discussed it before:

Parameterized modules in Erlang

This is neat stuff, and it's actually been included in recent versions of Erlang. I once toyed with the idea of a language which emphasized an OO style with stateless objects (relying on Erlang-style concurrency patterns for management of state). It seems like Erlang has just made a huge leap toward being that language.

The caveat, though, is that I'm not actually an Erlang programmer, only an interested observer. Do any of the local Erlang folks have any thoughts on this?
