Macpascal and Iso pascal have procedural parameters, e.g.
function A( function B: double): double;
Is there a $modeswitch to allow this ? I searched "procedure parameter"
and "procedural parameter" in the Language Reference, but could not find
anything.
As far as I know, the above is not allowed. you must declare the callback
type explicitly.
It can in iso and macpascal mode. Read the Pascal standard.
It's not because something is in the pascal standard, that FPC has it.
But if so, I was unaware and in that case I will document it.
Why they would put something as unreadable as that in the standard is a
mystery to me.
