-Tuples can be expanded and merged like this:
-```kotlin
-// expand
-tupleOf(1, 2).appendedBy(3) == tupleOf(1, 2, 3)
-tupleOf(1, 2) + 3 == tupleOf(1, 2, 3)
-tupleOf(2, 3).prependedBy(1) == tupleOf(1, 2, 3)
-1 + tupleOf(2, 3) == tupleOf(1, 2, 3)
-
-// merge
-tupleOf(1, 2) concat tupleOf(3, 4) == tupleOf(1, 2, 3, 4)
-tupleOf(1, 2) + tupleOf(3, 4) == tupleOf(1, 2, 3, 4)
-
-// extend tuple instead of merging with it
-tupleOf(1, 2).appendedBy(tupleOf(3, 4)) == tupleOf(1, 2, tupleOf(3, 4))
-tupleOf(1, 2) + tupleOf(tupleOf(3, 4)) == tupleOf(1, 2, tupleOf(3, 4))
-```
-
-The concept of `EmptyTuple` from Scala 3 is also already present:
-```kotlin
-tupleOf(1).dropLast() == tupleOf() == emptyTuple()
-```
-
-Finally, all these tuple helper functions are also baked in:
-
-- `componentX()` for destructuring: `val (a, b) = tuple`
-- `dropLast() / dropFirst()`
-- `contains(x)` for `if (x in tuple) { ... }` 
-- `iterator()` for `for (x in tuple) { ... }`
-- `asIterable()`
-- `size`
-- `get(n) / get(i..j)` for `tuple[1] / tuple[i..j]`
-- `getOrNull(n) / getOrNull(i..j)`
-- `getAs<T>(n) / getAs<T>(i..j)`
-- `getAsOrNull<T>(n) / getAsOrNull<T>(i..j)`
-- `copy(_1 = ..., _5 = ...)`
-- `first() / last()`
-- `_1`, `_6` etc. (instead of `_1()`, `_6()`)
-- `zip`
-- `dropN() / dropLastN()`
-- `takeN() / takeLastN()`
-- `splitAtN()`
-- `map`
-- `cast`
