+ * a regexp to make sure we extract the name properly.
+ *
+ * Here we assume that f has been defined by means of a function statement,
+ * and not a function expression (where it wouldn't have to have a name).
+ *
+ * Rhino uses a Unicode representation for f.toString(); whereas
+ * SpiderMonkey uses an ASCII representation, putting escape sequences
+ * for non-ASCII characters. For example, if a function is called f\u02B1,
+ * then in Rhino the toString() method will present a 2-character Unicode
+ * string for its name, whereas SpiderMonkey will present a 7-character
+ * ASCII string for its name: the string literal 'f\u02B1'.
+ *
+ * So we force the lexer to condense the string before using it.
+ * This will give uniform results in Rhino and SpiderMonkey.

+ * Note we can't simply do |eval(str)|, since in practice |str| will be an
