Suggestion:
* {@return a human-readable name for this {@code ClassDesc}}
* For primitive types, this method returns the simple name (for example
{@code int}).
* For class or interface types, this method returns the unqualified class
name.
* For array types, this method returns the human-readable name of the
component
* type suffixed with the appropriate number of {@code []} pairs.
