Using uninitialised variables is virtually always bad, regardless of the

I think I didn't get your point. What about this piece of code:
interface
function foo: tfoo;
implementation
var
_foo: tfoo;
function foo: tfoo;
begin
if not assigned(_foo) then
_foo := tfoo.create;
result := _foo;
end;
Is it safe?
