If you wanted to use Object Pascal today and not have to rely on Embarcadero for the continued support of your tools you could use Free Pascal and Lazarus, which are both free software (GPL-licensed). Unfortunately, there's bit of a stigma against using any variant of Pascal these days (to which, no doubt, the many crappy CRUD apps written in Delphi and Borland's management of their product have both contributed), so it's not a good choice for new projects, especially free and open source. I wonder if Nimrod could be the comeback of type-safe compiled languages that don't target the JVM.
