Now, to make this thread on-topic: is anybody working on a C++11 rewrite of Boost.MPL?

Anyone attempting such a rewrite and planning to use the variadic template features might want to start from:

http://svn.boost.org/svn/boost/sandbox/variadic_templates/boost/mpl/

However, using variadic templates may cause a slowdown in the compile times. IIRC, a variadic template version of proto was developed but was abandoned in favor of using:

http://www.boost.org/doc/libs/1_51_0/libs/preprocessor/doc/index.html

because of large compile times.

Hm.

This is really sad if variadic templates can't be used for the thing they were created for. Is this an inherent problem for large-scale use of variadic templates?

In another post, Eric Niebler reported that Walter Bright seems to think there's an inherent problem with the way c++ does templates. I recently asked Walter for more details here: http://www.digitalmars.com/d/archives/c++/why_are_c_template_instantiations_... -Larry
