[Expectperl-discuss] quotes around $scalar

[Blackstone, J. D. <jda...@ci...>]

  Just got back from a week off, and I saw the discussion about

$x->expect($t, '-re' => "$regex");

  As many mentioned, putting quotes around the $regex is unnecessary and may
cause problems.  This is true in general for any scalar.  The only time you
want quotes is when you want to do "other text $scalar more text."

  In fact, this is in the Perl FAQ in perlfaq4 under "What's wrong with
always quoting "$vars"".
