NAME
   Devel::Leak::Cb - Detect leaked callbacks

VERSION
   Version 0.04

SYNOPSIS
       use Devel::Leak::Cb;

       AnyEvent->timer( after => 1, cb => cb {
       ...
       });

       # If $ENV{DEBUG_CB} is true and callback not destroyed till END, the you'll be noticed

DESCRIPTION
   By default, cb { .. } will be rewritten as sub { .. } using
   Devel::Declare and will give no additional cost at runtime

   When $ENV{DEBUG_CB} will be set, then all cb {} declarations will be
   counted, and if some of them will not be destroyed till the END stage,
   you'll be warned

EXPORT
   Exports a single function: cb {}, which would be rewritten as sub {}
   when $ENV{DEBUG_CB} is not in effect

   If "DEBUG_CB" > 1 and Devel::FindRef is installed, then output will
   include reference tree of leaked callbacks

FUNCTIONS
 cb {}
   Create anonymous callback

       my $cb = cb {};

 cb name {}
   Create named callback with static name (Have no effect without
   $ENV{DEBUG_CB})

       my $cb = cb mycallback {};

 cb $name {}
   Create named callback with dynamic name (Have no effect without
   $ENV{DEBUG_CB}) $name could me only simple scalar identifier, without
   any special symbols

       my $cb = cb $name {};
       my $cb = cb $full::name {};

 cb 'name' {}
   Create named callback with dynamic name (Have no effect without
   $ENV{DEBUG_CB}) Currently supported only ' and ". Quote-like operators
   support will be later

       my $cb = cb 'name' {};
       my $cb = cb "name.$val" {};
