[ID 20010425.010] use re "debug" not debugging
Message ID:
E14sYXy-0002x8-00@ns0.astray.com

This is a bug report for perl from acme@astray.com,
generated with the help of perlbug 1.33 running under perl v5.7.1.


-----------------------------------------------------------------
[Please enter your report here]

ext/re/re.pm says:

  When C<use re 'debug'> is in effect, perl emits debugging messages when
  compiling and using regular expressions.  

Under old perls this is true. eg 5.6.0:
[acme@tigger re]$ perl -e 'use re "debug"; qr/^foo$/'
Compiling REx `^foo$'
size 5 first at 2
   1: BOL(2)
   2: EXACT <foo>(4)
   4: EOL(5)
   5: END(0)
anchored `foo'$ at 0 (checking anchored) anchored(BOL) minlen 3 
Freeing REx: `^foo$'

However, for perl-current synced 20 mins ago gives nothing:
[acme@tigger re]$ perl5.7.1 -e 'use re "debug"; qr/^foo$/'

I don't have enough tuits to figure out why this is the case (or what
has changed), but it would be really nice if the old, documented
behaviour came back so I could draw some more pretty graphs ;-)

[Please do not change anything below this line]
