in thread use and require inside subs

You can't hide a use like that.

if (0) { print "This block is happening!\n"; use Win32; } print "$_\n" for keys %INC; __DATA__ warnings/ <------- Perl sees all uses (almost)

And on a system where the module is not available......

[root@devel3 root]# cat #!/usr/bin/perl -wT BEGIN{print "We are on $^O\n"} if ($^O eq 'MSWin32') { use Win32::TieRegistry( Delimiter=>"/", ArrayValues=>0 ); # load $config from registry } else { # else load $config from flat files } [root@devel3 root]# ./ We are on linux Can't locate Win32/ in @INC (@INC contains: /usr/local/l +ib/perl5/5.6.2/i686-linux /usr/local/lib/perl5/5.6.2 /usr/local/lib/p +erl5/site_perl/5.6.2/i686-linux /usr/local/lib/perl5/site_perl/5.6.2 +/usr/local/lib/perl5/site_perl) at ./ line 4.
