The iso feature supports a third, namely recursive programming, which has
been forgotten after C took over the world and introduced its assembly
style programming.

There is a lot of existing code out there which currently are not
supported by any live compiler, namely everything written in some of the
mac pascals. FPC can be the remedy.

As I see the suggested solution, the iso stuff can be added, without
affecting existing code.
