Add operator (e1.operator_add(e2))

[Jon Rustand]

Hi,

In the code sample below, two Path elements are added (one for data and one for temp), is this a bug ?

import java.util.List

import java.nio.file.Path

import java.util.ArrayList

import java.nio.file.Paths

class PathAdd {

def static void main(String[] args) {

val List<Path> paths = new ArrayList

val path = Paths.get('c:/data/temp')

paths += path

println(paths.size) // => 2

}

}

Regards

When in doubts, look at generated code to see what is happening (Windows->Show View, Xtend->Generated Code).

final Path path = Paths.get("c:/data/temp");
Iterables.<Path>addAll(paths, path);

As Path is Iterable, += is interpreted as addAll, rather than just add.
