I basically want to put a wrapper around a function when it's declared with a particular attribute. This would normally be easy, because when the handler is run, you get a reference to the symbol, so you can do this:

   sub myhandler : ATTR(CODE) {
      my($pkg, $symbol, $referent....) = @_;
      ...
      *{$symbol} = sub {
          # additional code
          goto &$referent;
       }
   }

However, the script(s) that uses the attribute is called from do(). That means that the CHECK and INIT blocks are not run. I tried changing the handler to be invoked at BEGIN time, but the problem there is that the $symbol is a string that says "ANON". So I have no where I can assign the newly generate sub.

Does anybody know a way to workaround this?
