You can declare a virtual function to not have an implementation by using <code>F.virtual.abstract</code> keyword. A type containing at least one abstract virtual function cannot be instantiated.
<lang 11l>T AbstractQueue
F.virtual.abstract enqueue(Int item) -> N
T PrintQueue(AbstractQueue)
F.virtual.assign enqueue(Int item) -> N
print(item)</lang>
