Doesn't the absence of an empty prototype in the assignment *$AUTOLOAD = sub { $val } mean that these are just normal (non-constant) subs, and will therefore never be inlined, and therefore, called everytime they are used? 

## From Socket.pm (Fnctl.pm contains an nearly identical sub)
sub AUTOLOAD {
    my($constname);
    ($constname = $AUTOLOAD) =~ s/.*:://;
    croak "&Socket::constant not defined" if $constname eq 'constant';
    my ($error, $val) = constant($constname);
    if ($error) {
    croak $error;
    }
    *$AUTOLOAD = sub { $val };
    goto &$AUTOLOAD;
}
