boost.tmp: your DSL for Metaprogramming
summary
A new DSL called boost.tmp implements tacit template metaprogramming in C++11, with lazy-by-default expression templates, pipe-like composition and a call macro that lets closures manipulate packs and short-circuit decisions. Benchmarks show order of magnitude faster type-manipulation than Hana and consistent speedups versus std traits (examples use 500-element lists and is_same microbenchmarks). It handles SFINAE via a maybe/nothing model and tag-dispatch to avoid exploding instantiations; prototype exists but remains young and experimental.
