[Grace-core] One True Message Send

[Andrew P. Black]

I edited the "One True Message Send" post too.

I thought that we had decided to allow variadic messages.  I must say that i don't see how to do it, but  it seemed like the right way to support library-defiend constructors for collections.

See the comment at the very end of the post.
