 #;1> (string-substitute
   "{12mp}"
   "TRUE"
   "{12mp}"
   #t)

 Error: (car) bad argument type: ()

         Call history:

         <syntax>                (string-substitute "{12mp}" "TRUE"
 "{12mp}" #t)
         <eval>          (string-substitute "{12mp}" "TRUE" "{12mp}" #t)
 <--
 #;1>

 The braces in the regexp are incorrect -- they needed backslashes -- but
 the resulting error is very unhelpful. The regexp is mal-formed, and the
 regexp compiler ought to say so.
