[Boost-users] Understanding how enable_if works.

Hi, I'm new to boost / generic programming and I'm trying to understand how enable_if works because I don't like using things I don't understand. I made a simple example which I thought would have the same behavior as using enable_if but doesn't. I've attached the test could someone take a look and explain why enable_if works and the other doesn't.
