That's not a matter of support, to writeln a record you must keep the
structure information at runtime which is a must for scripted
languages but it is not needed at all for a compiled one (native
code). So if you keep that information people will complaint about
memory footprint and compiler not hidding internal program structures
and other now complaint about it can not writeln a record :-?

If you want to do something like that replace yout records with
classes and put the fileds in the published section so you will have
RTTI information about the class and you can write a generic writeln
function for classes writting the published fields.
