in thread Let a module call a sub of the caller

I just wanted to facilitate the use of a Module and avoid exorting into the caller's namespace. In particular, the Module does not just call the method but does some processing to pass it the right parameters. The same could be done with an export:

use My::Module qw(call); call(\&foo); sub foo { ... };

I am not that familiar with the processing phases BEGIN,INIT,END, that's why I asked. Is there a way to call the method at the END of execution of the caller?:

use My::Module call => 'foo'; sub foo { ... }; # foo is called at the end

    END time is the same for all, so yes, that works:

    # file CallMe.pm package CallMe; use 5.010; use strict; use warnings; my @to_call; sub import { my ($self, @routines) = @_; my $call_package = (caller(1))[0]; push @to_call, $call_package. "::$_" for @routines; } END { no strict 'refs'; $_->() for @to_call; } 1;

    And then in your script:

    use 5.010; use lib '.'; use CallMe 'foo'; sub foo { say 42 } say 'in mainline';

    prints

    in mainline 42
