in thread Passing filehandles to subroutines

John,

This is very cool. I like this method. Do you have any idea if this is going to be supported in Perl 6? Or, perhaps I should ask, is this 'kosher'? This isn't a "may be removed if we feel like it" feature, is it?

Thanks!

    See if you can find my thread via super search or skimming the list of nodes I posted. That is when I asked if it was 'kosher' and got a lot of remarks about it. What I remember: yes, it is proper and will work moving forward, but doesn't work on older versions (I don't remember when) so it is an issue if you need to run on older stuff, but no other issues impressed me enough to remember or disuade me.

      I think it's supported since version 5.6.

    It's pretty normal as far as I know, I use it all the time. Look at the perlsub documentation about passing around filehandles.
