+ * TraceKit.report: cross-browser processing of unhandled exceptions
+ *
+ * Syntax:

+ *   TraceKit.report.unsubscribe(function(stackInfo) { ... })
+ *   TraceKit.report(exception)
+ *   try { ...code... } catch(ex) { TraceKit.report(ex); }
+ *
+ * Supports:
+ *   - Firefox: full stack trace with line numbers, plus column number
+ *              on top frame; column number is not guaranteed
+ *   - Opera:   full stack trace with line and column numbers
+ *   - Chrome:  full stack trace with line and column numbers
+ *   - Safari:  line and column number for the top frame only; some frames
+ *              may be missing, and column number is not guaranteed
+ *   - IE:      line and column number for the top frame only; some frames
+ *              may be missing, and column number is not guaranteed
+ *
+ * In theory, TraceKit should work on all of the following versions:
+ *   - IE5.5+ (only 8.0 tested)
+ *   - Firefox 0.9+ (only 3.5+ tested)
+ *   - Opera 7+ (only 10.50 tested; versions 9 and earlier may require
+ *     Exceptions Have Stacktrace to be enabled in opera:config)
+ *   - Safari 3+ (only 4+ tested)
+ *   - Chrome 1+ (only 5+ tested)
+ *   - Konqueror 3.5+ (untested)
+ *
+ * Requires TraceKit.computeStackTrace.
+ *
+ * Tries to catch all unhandled exceptions and report them to the
+ * subscribed handlers. Please note that TraceKit.report will rethrow the
+ * exception. This is REQUIRED in order to get a useful stack trace in IE.
+ * If the exception does not reach the top of the browser, you will only
+ * get a stack trace from the point where TraceKit.report was called.
+ *
+ * Handlers receive a stackInfo object as described in the
+ * TraceKit.computeStackTrace docs.

+ *   s.stack[i].args     - arguments passed to the function, if known
+ *   s.stack[i].line     - line number, if known
+ *   s.stack[i].column   - column number, if known
+ *
+ * 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
