"Things"?  Plural?  I've only cut one thing (apart from misleading or
content-free narrative) is the symref solution.  This solution is of
negledgible potential use - it old FAQ more-or-less admits this.

I can see this, maybe.  

Question 1:

  How can I apply Perl interpolation to a string?

  [ all about chop($text = eval"<<END\n$text\nEND\n") ]

  See also ``How do I make a text templating system in Perl?''

Question 2:

  How do I make a text template in Perl?

  [ all the stuff from the old FAQ plus mention of sprintf, format and
  the Templating modules on CPAN ]

  See also ``How can I apply Perl interpolation to a string?''

I must admit I had not expected a debate - I thought it was
overwhelmingly accepted that this FAQ was wrong and needed to be fixed
so that it actually answered the question that was frequently asked.

I can't believe that anyone who has thought about it would disagree
that the answer to the question that is frequently asked is chop(
$text = eval "<<END\n$text\nEND\n").

Can't we just commit and move on?

If you think we need to split this so that we can have a more extensive
FAQ entry about text templates in general then that should be
addressed as a separate issue.

BTW: Where can I find an archive of [email protected]?
