// Invoke a function and returns it result.
// All parameters are forwarded.

// Why using `invoke()`?
// - avoid tedious IIFE syntax
// - avoid declaring variables in the common scope
// - monkey-patching

// ```js
// const sum = invoke(1, 2, (a, b) => a + b)

// eventEmitter.emit = invoke(eventEmitter.emit, emit => function (event) {
// if (event === 'foo') {
// throw new Error('event foo is disabled')
// }
//
// return emit.apply(this, arguments)
// })
