Lambda the Ultimate

Hello All:
I have written a log function to the project. Depending on the level in the log function(INFO) it displays the message. But in the log fn. i have a -if- which is called each time log is being called( like having an -if- for each printf of C). Is there a way to avoid the
-if- in the log function.
My Log call looks like:

LOG(INFO,"This Belongs to INFO Mode");
//INFO is of enum type

I wouldn't normally think a library is LtU material, but since this one lives at the intersection of embedded DSLs, process calculi, and a spotlight language, I think it fits: Communicating Scala Objects, Bernard Sufrin, Communicating Process Architectures 2008.

In this paper we introduce the core features of CSO (Communicating Scala Objects) – a notationally convenient embedding of the essence of occam in a modern, generically typed, object-oriented programming language that is compiled to Java Virtual Machine (JVM) code.

If you would like to play with it, the library can be downloaded here.
