def unsafeLabel(msg: String): Parsley[A]

Sets the expected message for a parser. If the parser fails then expected msg will added to the error. This will supercede '''all''' labels that that are present in the parser p. Whilst this does improve the speed of the parser, it may render your error messages useless if not used carefully. This method should ''only'' be used for '''non-terminals''' in the grammar
