Various current proposals for Function.bind have a drawback that in a
typical situation one needs to use the reference to the object twice

obj.method.bind(obj)
This is common, but not majority-case from a quick survey:
$ find dojotoolkit.org MochiKit prototypejs.org -name '*.js' -print |
xargs fgrep .bind\( | wc -l
40
$ find dojotoolkit.org MochiKit prototypejs.org -name '*.js' -print |
xargs fgrep .bind\( | /tmp/findbind.pl | wc -l
18
where findbind.pl looks for /\b(\w+)\.\w+\.bind\(\1[,)]/
(obj.method.bind(obj...).
Anyway, bind is being standardized based on the de-facto standard, the
common intersection semantics among popular Ajax libraries' bind-like
methods (jQuery has a different bind so I left it out of my find above).
obj.bind.method
With such short form the need, for example, for Array methods taking
an extra thisObj argument would be pretty much removed.
This is cool, although perhaps the name should be something else:
obj.bindSelfTo.method
or just
obj.bindTo.method
Don't want to get all long-winded, but do want to avoid overloading
the ever-popular "bind".
