execute() public method

The code has to be designed in a way that it can be repeated without any side effects. When execution was successful it should notify that event by calling {@link Loop::end()}. I.e. the only side effects of the code may happen after a successful execution. If the code throws an exception it will stop repeating the execution.
public execute ( callable $code ) : mixed
$code callable The executed code block.
return mixed The return value of the executed block.
