Class naming and package organization in Dynalink should be improved. All package and type names below are presumed to be named relative to the Dynalink package itself. Specifically:

1. linker.GuardedInvocationFilter should be renamed to linker.GuardedInvocationTransformer. "Filter" implies a predicate; this interface OTOH takes and returns a GuardedInvocation.

2. a new package for classes supporting the linker package should be introduced, named linker.support. These classes were so far in the support package. The classes in question are: support.CompositeGuardingDynamicLinker, support.CompositeTypeBasedGuardingDynamicLinker, support.DefaultInternalObjectFilter, support.Guards, support.Lookup, support.SimpleLinkRequest, support.TypeUtilities,

3. MonomorphicCallSite should be renamed to SimpleRelinkableCallSite (in keeping with the principle of naming simplest possible implementations) and moved to support package

4. ChainedCallSite should be moved to support package
