### New tab-completion in the Scala REPL
16+
- #5730 Allow user-defined apply/unapply method in case class companion under `-Xsource:2.12` (improved by #5828 in 2.11.10 and #5846 in 2.11.11)
17+
- #5821 Revert #5664 because the binary incompatible change leaks via erasure (in 2.11.10)

The implementation of tab-completion in the Scala REPL has been rewritten and now uses the same infrastructure as for example Scala IDE and ENSIME.

* Reliable completion, also in partial expressions and syntactically incorrect programs: try `class C { def f(l: List[Int]) = l.<TAB>`
21-
* CamelCase completion: try `(l: List[Int]).rro<TAB>`, it expands to `(l: List[Int]).reduceRightOption`
22-
* Show desugarings performed by the compiler by adding `//print`: try `for (x <- 1 to 10) println(x) //print<TAB>`
23-
* Complete bean getters without typing `get`: try `(d: java.util.Date).day<TAB>`
24-
* Find members by typing any CamelCased part of the name: try `classOf[String].typ<TAB>` to get `getAnnotationsByType`, `getComponentType` and others
25-
* Complete non-qualified names, including types: try `def f(s: Str<TAB>`
26-
* Press tab twice to see the method signature: try `List(1,2,3).part<TAB>`, which completes to `List(1,2,3).partition`; press tab again to display `def partition(p: Int => Boolean): (List[Int], List[Int])`
