The changes seem safe enough from a really quick look, but I
personally dislike having statements like

  return someOtherFunction(with,
                           its,
                           own,
                           parameters);

unless the calling function is a very straightforward wrapper,
eg. the return statement is the only one in the body.

That's of course just my personal taste :)

Cheers.
