I’m not sure whether this intended behaviour or not, but here it is anyway.

The idea is to have a function return the size of a List regardless of the type of objects inside:

function sizeOfList(l : List<Entity>) : Int {
var i : Int := 0;
for(k : Entity in l){
	i := i + 1;
}
return i;
}

This passes by Eclipse plugin just fine. When attempting to build it results in the following error:
