Welcome to JavaScript.
That's pretty much what bind does, but Function.prototype.call and
Function.prototype.apply let you jigger "this" for a given call.
foo.bar(a, b) is the same as foo.bar.apply(foo, [a, b]) or
foo.bar.call(foo, a, b).

Well you give it 'this' as the second argument, it doesn't do all that
much magic.
bind(test.myfunc, test) is equivalent to function () { return
test.myfunc.apply(test, arguments); }
