A facility for getting the current method's name

[Krystal Mok]

Hi Behrang,

This reminds me of how people were looking for a "current class literal",
something like this:

public class Foo {
  public static void main(String[] args) {
    // don't want to hard code "Foo.class" here
    String name = Foo.class.getName();
  }
}

and now that JDK7 is out, they've got a new toy that gives them exactly
that:

java.lang.invoke.MethodHandles.lookup().lookupClass()

It's not mean't to be fast when used like this, though.
The same with what you're looking for, but you've already got backtrace
which gives you the correct semantics, just not fast enough, right?

They don't seem to be expensive in JavaScript or Ruby because those
languages didn't have fast implementations. Once they do (as the current JS
engines and JRuby/Rubinius), this kind of reflective operations will show
their cost.
