Hi Marcel,

Just speaking about the constructor, I've long wished to be able to create
MessageSend's with brevity like that.  I actually wish the traditional
Smalltalk API would have been *outward-looking*, by having #>> answer a
MessageSend, instead inward-looking and answering a CompiledMethod.  What
do *users* of Smalltalk want to ever do with CompiledMethods?  Nothing.

But, I actually don't think it's too late.  There's no need to give up
availability of #>>> (which I think *is* used by some frameworks -- I could
be wrong) from the namespace.  Instead, I think we should simply overload
#>> on Object and not worry about it.  If any code actually *needs* to
create a MessageSend to a Behavior (probably a rare thing), they could
still use the wordy constructor we're all still using to this day.

Okay, so there's Integer, too.  That's fine.  We're just talking about
syntax-sugar here.  We'll have to continue to create our MessageSend's to
Integer's the long way, which is what we're still doing, so, no big deal!
:)

See Kernel-cmm.1489.   I held off on that sugar to "*append"* arguments
because it might be counterintuitive by the fact the #selector of a
MessageSend is just set once and specifies a fixed number of arguments from
the get go.  So, it might be better for usage of the arguments API to match
#selector's.

Best,
  Chris
