// lookupFunction returns a Decl proto for typeName as a function in env.
// Returns nil if no such function is found in env.
func (e *Env) lookupFunction(name string) *decls.FunctionDecl {
	for _, candidate := range e.container.ResolveCandidateNames(name) {
		if fn := e.declarations.FindFunction(candidate); fn != nil {
			return fn
		}
	}
	return nil
}

// setFunction adds the function Decl to the Env.
// Adds a function decl if one doesn't already exist, then adds all overloads from the Decl.
