I don't see the point. If that's what you like, use jQuery.

Comment 3 Aryeh Gregor 2010-11-01 20:00:30 UTC 
This is nice in jQuery because it sometimes lets you avoid naming extra variables, e.g. (actual code sample I was just looking at)

  $("body").append("<script></script>").attr("src", foo);

rather than

  var script = document.createElement("script");
  script.src = foo;
  document.body.appendChild(script);

which is necessary when using DOM methods because "script.src = foo" and the equivalent setAttribute() call don't return the element they're operating on, so you need an explicit temporary variable.  But almost any real-world canvas use is going to want to keep around a context handler anyway, so it doesn't look like there's any gain here.  (Although I don't see the harm either.)

Status: Rejected
Change Description: no spec change
Rationale: Returning self isn't a good design pattern IMHO. It leads to very odd APIs that favour syntactic sugar over conveying logic.
