Returns a boolean results (true or false) depending on whether all of the code-blocks included as parameters are successful or not.

}and does not set the exit number on failure so it is safe to use inside a try or trypipe block.
If and is prefixed by a bang then it returns true only when all code-blocks are unsuccessful.
