Removed Type-Defect label.
Added Type-Enhancement label.

It sounds like there are two changes here. One is just a change from <anonymous closure> ==> {}. The other is to include the names of the enclosing scopes (CodeEmitterTask.{} ==> CodeEmitterTask.assembleProgram.{}).

The VM now provides all the additional info. I'll let Devon close this issue once the editor exposes all of it to the user.

Set owner to @devoncarew.

I don't see VM providing enough info.

Test code:

import 'dart:async';

main() {
  fooBar();
  new A().barBaz();
  new Future(() {
    print('aaa');
  });
}

fooBar() {
  new Future(() {
    print('bbb');
  });
}

class A {
  barBaz() {
    new Future(() {
      print('ccc');
    });
  }
}

Stack trace for breakpoint on print('bbb'), see formatted output as the first attached image.
Note that the first "functionName", in test2.dart is just "<anonymous closure>" without specifying that it is in "main".

  The same is for A.barBaz().
  See the second attached image.
  Again, we see just "A.<anonymous closure>", but not the name of the method in A where it is, i.e. "A.barBaz.<anonymous closure>".

My comment #­10 is referring to closure objects, not function/closure names. This is still a valid feature wish.
