TIL 'evaluable' means 'able to be evaluated'! https://english.stackexchange.com/questions/304948/evaluable-vs-evaluatable

const fnwere mentioned in the title, but called "deterministic functions" which is not their main property (though at least currently it is a consequence of being const-evaluable). This adds a brief paragraph discussing them, also in the hopes of clarifying that they do not have any effect on run-time uses.
