function baz() {
console.warn(new Deprecation("[my-lib] foo() is deprecated, use bar()"));

const Deprecation = require("deprecation");
const once = require("once");
const deprecateFoo = once(console.warn);
function foo() {
deprecateFoo(new Deprecation("[my-lib] foo() is deprecated, use bar()"));
}
foo();
foo(); // logs nothing
