+ * 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

+ *
+ * Tries to guess names of anonymous functions by looking for assignments

+ * 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.

+ *
+ * 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
