PROPOSAL: Method and Field Literals

[Roel Spilker]

About the remaining 4000: the search did not take into account that the
proposal could only be used in cases where you now use a String literal. The
search also gives results for invocations with a String variable, for
instance names that are read from a configuration file. So that will remove
some more.

Secondly, the proposal only allows Field and Method literals that are
visible to the caller. But my experience is that I use reflection often to
access private members of other classes. So more false positives in the
search results.
