Multiplexing channels

Multiplexing describes the methodology where we use a single resource to act upon multiple signals or actions. This method is used extensively in telecommunications and computer networks. We might find ourselves in a situation where we have multiple types of tasks that we want to execute. However, they can only be executed in mutual exclusion, or they need to work on a shared resource. For this, we make use of a pattern in Go known as channels multiplexing. Before we dive into how to actually multiplex channels, let's try to implement it on our own.

Imagine that we have a set of channels and we want to act on them as soon as data is sent over a channel. Here's a naïve approach on how we want to do this:
