That looks very reasonable.

And thanks, Albertina, for the detailed reference on the link between 
Actors (Plasma, in particular) and Smalltalk. Note that the Smalltalk 
described there (Smalltalk-72 as I had mentioned) was significantly 
different from Smalltalk-76 and later. It had a token stream message 
passing (mentioned in the text you cited) which was generalized as mail 
boxes in Actors. It had classes but these weren't objects (a limitation 
languages like C++ still have today). Each class had a single script 
instead of methods, just like Actors.
