That taken alone would have meant a step backwards: proper integers have
become non-integers, just to follow the errors of the majority in the
last decades.

Luckily the situation is not as bad, and David Matthews continues to
consolidate the new compiler and run-time system: Isabelle is already a
bit faster than before, while still remaining true to mathematical
semantics of int.

More tuning and measurements will follow in the coming weeks/months ...
