aliases

you can only use method names that are defined _somewhere_, e.g. you could lift A to another type, a wrapper ("pimp") that has fingers. but you cannot have a general doesNotUnderstand fall-back like in smalltalk, unfortunately...

The syntax for what you want is

  val a = new A { def fingers = x }

which will create a custom class which has x aliased to fingers.  (Actually it is a separate method, but the JVM will inline it for you, so there's no penalty.)

Hi,

Small thing: Is it possible to use aliases for methods in the following sense:

class A(name: String) {
 val x = 5
 ... Missing bit ...
}

enabling the usage

val a = new A("fingers")
println(a.fingers)

giving 5
