Well, with Pascal's syntax you could link through VMT fragments, without actually bouncing through additional code. And you don't risk forgetting adding a method to existing classes if you add one to the interface, always a risk with manual workarounds like the codegeneration tools that assume everything is designed at once top-down and only then implemented. _______________________________________________ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other
