What then is the nesting for if the command will only apply to the last

of the enclosing element?
What is the rationale for such a statement, ie using multliple elements?
Consider this example:
=== code begin ===
type
TTest1 = class
procedure Foo;
end;
TTest2 = class
proceduer Bar;
end;
// implementation of TTest1 and TTest2
var
t1: TTest1;
t2: TTest2;
begin
with t1, t2 do begin
Foo; // calls t1.Foo
Bar; // calls t2.Bar
end;
// same as:
with t1 do begin
with t2 do begin
Foo;
Bar;
end;
end;
end.
=== code end ===
"with" simply allows you to avoid some typing and evaluatios the
expression between the "with" and "do" only once (take a function for
example instead of "t1"). So mostly it's merely syntactic sugar.
