Aurelia failed binding not throwing error?

I was wondering if aurelia should throw error on failed binding ? I use durandal a lot, and a useful feature was "binder.throwOnErrors = true;" If a binding failed it would throw an error in the console.

But in aurelia, say i got a "version" var in my VM. If i bind 

${non-existing-var}

or even

${non-existing-object.non-existing-property}

it won't say anything.

So far aurelia is good, but sometimes it's a real pain to dig the template and to figure why the binding ain't working.

I've tried to dig in the aurelia-binding class, but could not find any clue. Thank you :)

I also use the default configuration (i see [Debug] logs in the console)

aurelia.use
  .standardConfiguration()
  .developmentLogging();

Aurelia does not throw when an attempt is made to bind to an null/undefined property (or chain of properties). This is intentional- Aurelia supports binding to things that aren't yet defined but will become defined later.

Other developers have requested an option log these occurrences be added. This request is tracked here.
