How do I make Ember Template Errors Verbose?

Currently, if you have an error in your handlebars/HTMLBars, there is a silent failure and instead of outputting html you get <!---->.

Is there a way to get an error message in the console or something to tell me what is wrong?

An example: http://ift.tt/216iUmk (I know what the error is, I want to figure out how to get an error message from Ember/HTMLBars)
