Bool assert

Bool assert is the final way to cause a panic in Gleam, used for writing test assertions. It is similar to let assert, except instead of asserting that a value matches a specific pattern, it asserts that a boolean value evaluates to True.

Like the other panicking keywords, the as keyword can be used to add a custom message to an assertion. This will be shown instead of the generic "Assertion failed" message if the value evaluates to False.

Bool assert is designed to be used in test code, and should almost never be used in applications or libraries.
