----------------------------------------------------------------- [Please enter your report here] Neither perlop.pod nor perlfunc.pod mentions that qr// returns a ref to the compiled regular expression. These patches fix that. Additionally, I've expanded the explanation of ref() to comment on how to create each type of reference. --- perlfunc.pod.orig Fri Mar 5 14:10:56 1999 +++ perlfunc.pod Mon Jun 7 15:10:48 1999 @@ -2781,6 +2781,13 @@ HASH CODE GLOB + Regexp + +References of types REF, ARRAY, HASH, and GLOB are simple to get with the +C<\> referencing operator.
