These efforts have been in support of the stated goal of making metaprogramming accessible to even novice developers. Unfortunately, the result is a complicated and unintuitive programming model. Elsewhere, an extremely compelling alternative that is intuitive and more powerful has been implemented in Sean Baxter's circle compiler. This talk describes the limitations of the constexpr metaprogramming model and introduces its persuasive alternative, circle metaprogramming. ------ David Sankel David Sankel is a Software Engineering Manager/TL at Bloomberg and an active member of the C++ Standardization Committee.
