> I'm not sure this was clear, but I think the clear goal for backwards compatibility is that code that used to run continues to run indefinitely. With no changes. That's certainly what the Racket core developers mean by "backwards compatible". In other words "requiring porting" is the opposite of "backwards compatible", at least in my mind.
I get this, but I think it's a strategic mistake. I think the goal should be to move people forward to the new versions (whenever they come out) as quickly as possible (think Apple and the rapid adoption of new iOS versions, compared to Microsoft). NEVER break people's stuff, but make it dead simple for them to upgrade to the new stuff, by changing their code for them. I think the success of Apple has proved this is the better long-term strategy. If Racket's truly a Language Oriented Programming language, than parsing it and upgrading it should be dead simple. Otherwise, why would I want to use a language that's difficult to upgrade?
