Objects as processes: Do you wrap message passing?

[Joel Reymont]

Howdy!

I'm implementing objects as "active processes" /is that the term?/ and
all the method calls are handled in a dispatch loop like this:

dispatch(This) ->
    receive
	
	{ Pid, bet_size, _, _, Stage } ->
	    Pid ! { retval, bet_size(This, Stage) },
	    dispatch(This);

...

	dispose ->
	    ok
    end.

Then I invoke the object like this:

Limit = fixed_limit:new(10, 20),
Limit ! { self(), bet_size, 0, 0, preflop },
{ Low, High } =  retrieve().

Do you usually add an extra layer on top of this by wrapping dispatch
functionality in a function? Is it better to add

bet_size(Limit, Foo, Bar, Stage) when pid(Limit) ->
    Limit ! { self(), bet_size, Foo, Bar, Stage },
    retrieve().

and then call 

fixed_limit:bet_size(Limit, ...)

    Thanks, Joel
