indylambda: Putting invokedynamic to work for Scala

indylambda: Putting invokedynamic to work for Scala

Java 8 introduced lambdas to the Java language. While the design choices differ in many regards from Scala's functions, the underlying mechanics used to represent Java lambdas is flexible enough to be used as a target for the Scala compiler.

Lambdas in Java

Java does not have canonical heirarchy of generic function types (ala scala.FunctionN), but instead allows a lambda to be used as a shorthand for an anonymous implementation of an Functional Interface

Here's an example of creating a predicate that closes over one value:

Better equality for Scala
import annotation.unchecked.uncheckedVariance
/** The trait of things that can be compared safely */
trait Equals[-T] {
/** A witness of Equals' type parameter. Should only used for
* the constraint in EqlDecorator, hence, @uncheckedVariance should not be a problem.
type EqualsDomain = T @uncheckedVariance
