#### assert
assert :: [predicate: nullary, message: string] -> (ok | failure)
assert returns either a failure or an ok with the message attached. It returns a failure with if the predicate thunk/nullary function returns a falsy value or a failure, or if it throws an error. It returns an ok otherwise (no errors, truthy value).

#### conform
conform :: [predicate: unary, value: any, message: string] -> (value | failure)
conform passes the value to the unary predicate. Returns the value for a truthy result, and returns a failure bearing the message with a falsy one, a failure, or a thrown error.

#### ok
ok :: [message: string] -> ok
ok returns an ok result with the message attached. The ok result is largely an internal affair of assert.

#### is_ok
is_ok :: [value: any] -> bool
is_ok does what it says on the tin: returns true if the value is an ok; returns false otherwise.

#### AssertionError
AssertionError :: [message: string] -> AssertionError
Returns an AssertionError` with the message attached.
