Pass a class subroutine as a callback

Question

I am using a module that takes callbacks (AnyEvent::Socket). I am trying to pass a class subroutine as a callback but nothing is working example:

tcp_server undef, $self->port,\$self->handle_connection

It just does not work, it complaints about undefined variables. if I pass the function as a anonymous subroutine it works

Answer 1

You can pass a anonymous function which calls object method,

sub{ $self->handle_connection }

Answer 2

The curry module was built for this sort of thing

use curry;

tcp_server undef, $self->port, $self->curry::handle_connection
