I am not supposed to put an ampersand in front of the constant,
because this is no longer needed for subroutines calls in PERL since
perl 5. But using the & triggers the responsible AUTOLOAD, while the
name is otherwise just treated as a bareword. This is apparently an
undocimented implementation quirk of the POSIX-module. Another version
that works:
use POSIX qw(sysconf);
sub POSIX::_SC_OPEN_MAX;
printf "%s\n", sysconf(POSIX::_SC_OPEN_MAX);
Another PERL oddity to know about ...
