Sorry if I overlooked something, but where is the variable of that type
declared in your code? These objects may be either declared statically
("var B: TBar") or dynamically ("Result := New (TBar.Init)" - but then the
return value must be of type PBar, not TBar).
Objects are like (advanced) records.
So Result is a TBar, and result already has the memory it needs. "New"
is not needed.
If I understand it
correctly, you initialize the object on the stack, but it would disappear
from there (gets overwritten) immediately after the function return (the
following function call would overwrite it).
It gets lost only, because i do not use the result of the function call.
But even if D did "SomVarBar := Foo;", I still get the warning.
