\caption{\label{fig:reflection-inference}%
Example inference rules for @ClassVal, @ClassBound, and @MethodVal.
Additional rules exist for expressions with similar semantics but that call
methods with different names or signatures.
%\todo{I added more examples and a more detailed description to the section, so
%    this does not seem to be necessary here: (e.g., @ClassVal is also inferred for
%calls to \<ClassLoader.loadClass>).}
