RE: [Boost-Users] A strange question-) What are Traits?

I have not been doing a large amount of Standard C++ for the last 2
years and seem to have fallen behind the times-) I'm catching up
(reading Alexandrescu) but got a way to go. One of the things that I
seem to have missed is traits? What are they? How do they relate to his
Policy classes? Since these are not Boost specific questions and are
more C++ questions is there a good C++ newsgroup that is recommended as
all the books I have don't seem to cover "advanced" topics well. Thanks
in advance.

How about the type traits remove_XXX templates?  Or even some of the
is_XXX
templates, although the latter tend to have rather a lot of workarounds
cluttering up the code.
