Relaxing Constraints on constexpr Functions

by Richard Smith

Excerpt:

This paper explores the removal of most of the restrictions on constexpr function definitions, in order to make them a simpler and more uniform extension of runtime C++ code. Idiomatic C++ code would be permitted within constexpr functions, usually with little or no modification from its non-constexpr form other than the addition of the constexpr keyword.
