No, you misunderstood. Scope correction means in an unbound event
handler, "this" will refer to the element you're calling observe *on*.
In the code above, you're calling observe on *document*, so "this" will
refer to document.
When you need to have methods as event handlers you need to specifically
bind; there's actually no technical way around it at all: JS does not
equip us with surefire means of detecting that the function we're
dealing with is a method (which would let us get rid of
bindAsEventListener, for instance), and even if it did, you wouldn't
necessarily want to bind to the owner object.
