If you only want that, why not use objects?
The real reason Jon Blow proposed this syntax is because it allows you keep
continuous arrays of memory which you can index into using struts.
The fact it mimics multiple inheritance (something Pascal doesn’t have anyways)
is just a bonus.
You can do that without the "with"
record TFoo
Bar: TOtherRecord; // has a field abc
end;
The only thing is that you need to access the field by its fully
qualified name Foo.Bar.abc, instead of Foo.abc.
Which is good, because you can have
record TFoo
Bar: TOtherRecord; // has a field abc
Other: TOtherRecord; // has a field abc
end;
and as with multiple inheritance "Foo.abc" would be ambiguous.
And as already was mentioned you can have properties to shortcut this.
But then the question came up why not:
record TFoo
Bar: POtherRecord; // pointer
property abc: xxx read Bar^.abc
end;
Well because abc may be nil. But then it is no longer "continuous memory"
