No changes are required per se, but the suggested modifications would
make the system simpler, smaller and more clean in my opinion.
Primitives would have a consistent syntax and would work searchable
such as senders and implementors of a method. Moreover no code would
be left over in the compiler package, namely the function
Parser>>#externalFunctionDeclaration could be part of the FFI package.

Of course I am wasting my time with minor details ;-)
