[Boost-users] starting to learn Boost MPL and type_trait

Hello all,
I am trying to start learning the Boost MPL. The internals are more
interesting for me then the usage I read both Abrahams&Gurtovoy and
Alexandrescu books (both excelent btw)

Some things i still don't quite understand:
1. How (or rather Why) does is_class works.
2. Same for is_enum 
3. Can someone explain how MPL lambda works specially how the "_" works

I tried to scan some of the archives but could not find any definite
answer - i guess the discussions if they were are lost.

P.S. neat trick to someone who try to learn the internals is to make a
program that just include the header u interested to learn and just do
the "pre-compile" stage (/EP /P flags in VC7.1 iirc) - you get a nice
header without the unreadable MACROS.

Thanks
