Tuple2 is a tuple with two values. It maps to an anonymous object with fields _0 and _1.
inline dropLeft ():Tuple1<T1>
dropLeft returns a new Tuple with one less element by dropping the first
on the left.
inline dropRight ():Tuple1<T0>
dropLeft returns a new Tuple with one less element by dropping the last
on the right.
inline flip ():Tuple2<T1, T0>
flip returns a new Tuple with the values in reverse order.
inline toString ():String
Provides a string representation of the Tuple
inline with<T2> (v:T2):Tuple3<T0, T1, T2>
Creates a new Tuple with the addition of the extra value v. The Tuple
of course increase in size by one.
staticinline of<A, B> (_0:A, _1:B):Tuple2<A, B>
Constructs an instance of Tuple2 the 2 required value. This is required
because Tuple2.new.bind(...) crashes the compiler.
