nit: I'd drop the .object sub-module namespace

[Ty Overby, 2013/07/29 23:26:56]

I disagree.  Usually forEach is defined on arrays/lists, but this makes it
explicitly obvious that it's being done on an object.  Otherwise, people might
think that 

  arr.forEach(fn);
and 
  util.forEach(obj, fn);

do the same thing if the variable names weren't so obvious.
