IIRC you can define a rc-file with perl-code which is sourced by each instance...

    Ok, but what should be the name of the rc-file and where is to be located?

      Finally I found what I had in mind, see $Config{sitelib}/sitecustomize.pl in perlrun

      But contrary to toolic's PERL5OPT it's site-wide, so better think twice about what could be affected.

      I said IIRC and your too fast! :)

      Couldn't find it seems I was confusing with the debugger or perl6 feature. Sorry!

      Anyway for the general problem it should be possible to alias perl to a command which loads a module first which does whatever settings you want.

      For your special problem the mentioned -E is good enough.

      Cheers Rolf
