Hi Monks,

Update: misunderstanding was somewhere else, this bit isn't the problem at all. Forget it!

I'm trying to understand what a bit of code is doing and I've got myself in a knot. In class A, there is a method that calls a class method of class B, with a code ref as an argument. Something like: 


#in class A
sub do_stuff{
    
   my $self = shift;  #1

   Class::B->do_things(sub{
                       my $self = @_; #2 
                  
                       my $blah = Class::C->blah({
                                   arg1=>$self->{blah}, #3
                                   arg2=>self->{wibble}
                                                 })    
                      }) 
}

So, which class do the $selfs in the call to do_things actually refer to?
#1 - Class::A
#2 - Is this Class::B as the code is actually executed in the context of that class or is it Class::A - and if so, why?
#3 - does the $self->{blah} get interpolated in the context of Class::A before the code ref is even created, or is it still $self->{blah} in the code, in which case it will refer to whatever #2 means.

Thanks for any help!
Cass
