also has an effect on return type declarations. In the default weak mode,
returned values will be coerced to the correct type if they are not
already of that type. In strong mode, the returned value must be of the
already of that type. If this type conversion is not allowed
(e.g. when returning an &array; from a function with return type &integer;),
a <classname>TypeError</classname> will be thrown.
In strict mode, the returned value must be of the
correct type, otherwise a <classname>TypeError</classname> will be thrown.
