This is a frequent pain point: protocol existentials cannot stand in for the
protocol they represent.
Your function wants a concrete type that conforms to ItemProtocol, but an array
of disparate types which happen to separately conform to ItemProtocol does not
do that.
You will need to overload thusly:
func someFunc(items: [ItemProtocol]) {
for item in items {
print(item.message)
}
}
until, someday, this pain point is resolved.
