tasks are not compilation units

Near the top of the page (https://learnxinyminutes.com/ada/)
it says:
-- Ada compilers accept compilation units which can be library packages,
-- tasks, sub-programs, generics, etc.

But tasks are not library units or compilation units.

The page doesn't otherwise mention tasks or protected objects.
It admits:
> I've only touched the surface, there's much more to look at in the references section below.

... but I think tasks and protected objects/types might be good to mention somewhere...
... just not in a statement that is false.
