What does that make me? Stone age? :-) Claw was mostly developed with versions of GNAT predating 3.15p (that was the first version that was really stable with Claw, with its heavy reliance on tagged types and finalization - both very new at the time). And, of course Janus/Ada goes back to 1980 (roughly 20 years before GNAT 3.15p). Randy.
