/**
 * For implementing declare @type interacting with declare @parents during compilation - we need to be able to add an annotation to
 * 'binary type binding' (this is how types are seen during incremental compilation). Unlike a SourceTypeBinding - a
 * BinaryTypeBinding does not allow easy interaction with its annotations - so what we do is take the eclipse annotation, suck out
 * the name/signature and visibility and put that information in a 'FakeAnnotation'. The FakeAnnotation is attached to the BCEL
 * delegate for the binary type binding - this will allow type resolution to succeed correctly. The FakeAnnotation never makes it to
 * disk, since the weaver does the job properly, attaching a real annotation.
