Interesting. That makes me wonder if there are other commands that I can make "behave like a platform" by not sending them as messages. And what different behaviors that would make possible. The platforms (like FitYbyX say) seem to behave the same whether sent as a message to a table or not but maybe there are also differences there? If I say dt<<Bivariate(..) am I making a platform behave as a command in some way that might make any difference? ( I do that all the time as it seems a less cumbersome way to make sure I'm talking to the correct table).
