    Type is the representation of a Go type.

    Not all methods apply to all kinds of types. Restrictions, if any, are noted in
    the documentation for each method. Use the Kind method to find out the kind of
    type before calling kind-specific methods. Calling a method inappropriate to the
    kind of type causes a run-time panic.
