Each method argument has the form: [<data type: bool|int|float|string>:]value

If you do not specify a data type, string will be assumed, otherwise
`value' will be converted to the given type first. The bool conversion
interprets each of 'True', 'true', '1', 'Yes', 'yes' as True, everything else
as False.
