   *   ```
   *
   * Supports:
   *   - Firefox:  full stack trace with line numbers and unreliable column
   *               number on top frame
   *   - Opera 10: full stack trace with line and column numbers
   *   - Opera 9-: full stack trace with line numbers
   *   - Chrome:   full stack trace with line and column numbers
   *   - Safari:   line and column number for the topmost stacktrace element
   *               only
   *   - IE:       no line numbers whatsoever
   *
   * Tries to guess names of anonymous functions by looking for assignments
   * in the source code. In IE and Safari, we have to guess source file names
   * by searching for function bodies inside all page scripts. This will not
   * work for scripts that are loaded cross-domain.
   * Here be dragons: some function names may be guessed incorrectly, and
   * duplicate functions may be mismatched.
   *
   * TraceKit.computeStackTrace should only be used for tracing purposes.
   * Logging of unhandled exceptions should be done with TraceKit.report,
   * which builds on top of TraceKit.computeStackTrace and provides better
   * IE support by utilizing the window.onerror event to retrieve information
   * about the top of the stack.
   *
   * Note: In IE and Safari, no stack trace is recorded on the Error object,
   * so computeStackTrace instead walks its *own* chain of callers.
   * This means that:
   *  * in Safari, some methods may be missing from the stack trace;
   *  * in IE, the topmost function in the stack trace will always be the
   *    caller of computeStackTrace.
   *
   * This is okay for tracing (because you are likely to be calling
   * computeStackTrace from the function you want to be the topmost element
   * of the stack trace anyway), but not okay for logging unhandled
   * exceptions (because your catch block will likely be far away from the
   * inner function that actually caused the exception).
   *
   * Tracing example:
   *  ```js
   *     function trace(message) {
   *         var stackInfo = TraceKit.computeStackTrace.ofCaller();
   *         var data = message + "\n";

   *             data += (item.func || '[anonymous]') + "() in " + item.url + ":" + (item.line || '0') + "\n";
   *         }
