So, from that point of view,

     begin <cmd>
     <parameter>
     <parameter>
     ...
     end

may be a better design, no?

Good point. Now I'm wondering if we can simplify where commands get queued up
and a "get" will execute them along with an implicit flush.

<cmd> <parameter>
<cmd> <parameter>
<cmd> <parameter>
get

I think that would be an improvement (I'd suggest calling "get" "flush" 
instead), the begin ... get <cmd> sequence seems unnecessarily complex 
compared the the RFC of this series. If the user gives --buffer on the 
command line then we can buffer the input until we see a "flush" command 
and if the user does not give --buffer on the command line then we 
should flush the output after each command.

Best Wishes
