That's true. But I am not happy about that approach. In the last years
lots of things were added to Pascal that are no longer clear and simple.
And most of them are of little use (for the programmer). They only
bloated the so small and easy to learn language.

In general that's true from the programmer's viewpoint. But this does
not apply to adding language details because there is no 'first make it
work'. Why obscure important implementation details if the only benefit
is saving some writing?

Maybe, but you started talking about performance. ;-)
