exactly what I was thinking :-)

A couple of other immutability thoughts; 
copying an imm. (I refuse to type it out every time) object - the copy primitive would need to clear the imm. bit unless we declare that a copy is also imm. In which case only ST code copying could be used to make non-imm. copies.
we’re SOL anytime any external prim or call is passed the guts of an imm. object.
