Add memoization for const function evaluations When a const function is being evaluated, as long as all its arguments are zero-sized-types (or it has no arguments) then we can trivially memoize the evaluation result using the existing query mechanism. 2019-11-11 14:32:36 +00:00			const fn a() -> usize { b() } //~ ERROR cycle detected when const-evaluating `a` [E0391]
