Inside the eventHandler this.scope is not set (as it's called on the scope itself)

Interestingly enough, this does not make any difference at all to any of the tests - I was trying to solve another problem with my code and just stumbled over this. Maybe someone can shed a bit light onto this line and what it does. @justinbmeyer maybe?
Implemented select with multiple-selection for can.view.bindings (i.e. two-way binding via can-value)
Also added tests that do pass with jQuery but fail every other library, because of a missing element.find()-function. I’d appreciate any input on making this work cross-library!
Fixed a small bug, the value must not be set directly as this confuses the browser.
Add breaking test for the index calculation (#552)
Calculate @index correctly for the can.List
Add `fromIndex` argument to all implementations of `can.inArray` (Mootools, Dojo, YUI)
better documentation around scope
improvements to helper options docs
Added test to issue
