Could we add something like an "Any" return type to Pascal which is a type that is compatible with any class? This relies on an event loop that can capture this garbage and dispose of it but it goes a LONG way in helping with common memory management problems.

That was a bad example. It's for ANY class really.

o := TObject.Create.AutoRelease;

Then next event cycle the autorelease pool frees all the objects added to it. Very simple but effective however we can't do this in Pascal without a new permissive return type.
