PUP-9753

Explanations to the above examples:

```

!$b

```

The ¡ is a boolean not, which requires a boolean value. To get one from any value, it checks if value is truthy or not:

false and undef become false
and all other values become true
The ! (not) operator then inverts the boolean

For the XOR operation

$a != $b

It does not matter if booleans are inverted or not since we are only concerned about values being different - i.e. the same result is obtained for true != false as for false != true.

As an extra: if you want a boolean reflecting the "truthy value" you can do !!$a, which first converts to inverted boolean and then inverts that to reflect the "truthyness" of the value.
