* Match guards as a separate syntax feature are important and necessary when we wish to concisely express more complex ideas than patterns alone would allow.
* They are not the same as separate `if` expression inside of the match arm. An `if` expression inside of the branch block (after `=>`) happens after the match arm is selected. Failing the `if` condition inside of that block won't result in other arms
of the original `match` expression being considered.
* You can use the variables defined in the pattern in your if expression.
