  <para>
   This function returns an multidimensional array containing a list of
   all defined functions, both built-in (internal) and user-defined. The
   internal functions will be accessible via
   <varname>$arr["internal"]</varname>, and the user defined ones using
   <varname>$arr["user"]</varname> (see example below).
