Details
(Whiteboard: [sp3])
When we're binding an already-bound function, we could be smarter and avoid the multiple levels of bound functions. This enables JIT bound function call optimizations. After the rewrite in bug 1483869 this should be possible now, so I'm filing this as future work.
What makes this annoying is that we need to preserve the original target too for instanceof (observable Symbol.hasInstance lookup, see this WebKit bug I filed).
