title: get sourcemapped source place in browser
body: <p>I have <code>window.onerror</code> and catching some exceptions. But the problem is that the stack trace is in JS that is compiled from another language (ClojureScript). So stack traces with line numbers are in compiled form. The question is: how to convert the stack to the original source in browser? As we can see browser is already able to use mapped sources in debugger. (We only use Chrome)</p>
