A big part of good API design is that we should be able to be flexible in
the ways that we take parameters.

Params::Coerce attempts to encourage this, by making it easier to take a
variety of different arguments, while adding negligible additional
complexity to your code.

What is Coercion
"Coercion" in computing terms generally refers to "implicit type
conversion". This is where data and object are converted from one type
to another behind the scenes, and you just just magically get what you
need.
