My understanding is that str($) results in a string literal of either of 
the two forms

   "\uXXXX"  "\UXXXXXXXX"

(where each "X" is a hex-digit).  Note that it does *not* result in a 
string literal of either of the two forms

   "\\uXXXX"  "\\UXXXXXXXX"

At least that is how I interpret 16.3.2/2.

On a related note, what puzzles *me* is what the string literal "\$" 
shall denote.
