I'm simply telling facts ...
It was the decision of the PL/1 language designers to make the
language more user friendly to the C community. You don't have to use
such language elements, if you don't like it. I see it this way: PL/1
is such a powerful language, that it even allows different programming
styles. Or: why not allow language constructs, as long as it is clear
to the programmer, what the new language element does and as long as
the spirit of the language is not broken?
BTW: variable ++; is not still possible in PL/1 for several good
In fact, we have much more C programmers out there than PL/1
programmers, and such possibilities may make it easier for them to
accept PL/1 as a second (third, forth) language.
