Scala: Abstract types vs generics
...T
...
}
and
class List[T] {...}
Then ListT is just the same as List[_].
The convience of type members is that we can use class without explicit concrete type and
avoid too many type parameters.

What is an optional value in Swift?
...t; = Optional("Bob")
This calls Optional's first initializer, public init(_ some: Wrapped), which infers the optional's associated type from the type used within the parentheses.
