I'm not exactly sure what the original poster wants, but I believe he already has a module full of subs. AUTOLOAD only gets called when a particular sub doesn't exist in that namespace, correct?

But I think it's a good idea -- if you can impose a wrapper over the orignal module, you can track all subsequent calls:

   package Foo;
   sub foo1 { ... }
   sub foo2 { ... }
   # etc
   1;

   package Wrapper;
   use Foo;
   use vars qw/ $AUTOLOAD /;

   sub AUTOLOAD
   {
       my $subname = $AUTOLOAD;
       $subname =~ s/.*:://;

       if( UNIVERSAL::can( 'Foo', $subname ) ) {
           print LOG "Foo::$subname called\n";
           return eval "Foo::$subname( \@_ )";
       } else {
           croak "No such sub: $AUTOLOAD";
       }
   }

This way you can keep track of exactly every subroutine call in Foo. Is that what you are saying?
