Exploring constexpr at Runtime

by Scott Schurr


The paper explores motivations for either a) constraining selected constexpr functions and constructors so they may only be used during translation, or b) overloading on constexpr so different implementations could be provided for translation-time vs. run-time execution. Two examples are examined for motivation. Then the paper explores four approaches to providing the constraints.
