Autoconf already uses perl to convert configure.ac into configure.  I
think you are asking what it would take to rewrite configure to use perl
rather than sh.  But what would it buy us?  sh is more portable than perl
(as measured by the number of platforms where it is included as part of n
a default bare-bones installation), and starts up considerably faster on
some platforms (cygwin, for example).  I will review any such patches to
use perl instead of shell, but I won't be writing any, nor will I be
advocating that someone invest the time into it.
