Of course, just a small joke.

In Axon, believe or not,  everything else except the core engine functions is
written in Delphi !

My opinion is that hybrid software architecture : Pascal or C for higher
recursive functions, PVS,null move etc. and machine language for the move
generator, evaluator, Qsearch… is the right combination.

In Axon the about 4000 lines are written in Delphi.

But all crucial speed-depended functions are enclosed in 50000 assembly lines !
