Title: Throw exception when undefined is passed to bindTo as first arguments

I noticed it quite hard to understand what's the problem
when accidentally passed undefined variable as first argument to bindTo method.
It requires to add breakpoint and investigate call stack. So I thought
it would be nice to have exception with friendly text.
