Hello wise monks!

I would like to ask a (probably) newbie question in regards to namespaces and names collisions.

Lets say that I have something like this in my code (shortened, incomplete).

    package Something::BufferedRead;
    use strict;
    use warnings FATAL => 'all';
    use File::Basename;

    our $VERSION                   = 1.00;
    my $BUFFER_SIZE                = 1048576;

    sub new {
        my $class = shift;
        my @data = @_;
        
        my $self = {};
        bless $self, $class;    
        return $self;
        
    }

    sub basename {
        my $self = shift;
        return basename($self->{cfg}->{filename});
    }

Now this fails to compile since 'basename' collides with name of sub imported from module File::Basename. Obvious solution would be to change name of my sub, for example to 'base_name', however I want to understand what exactly is going on, and how to prevent this from being pain in the future.

Which leads me to the real question.

• Is there aby way how to prevent File:::Basename->basename from becoming a member of Something::BufferedRead namespace?
• How exactly does one influence what is imported from the module used? I am sure this has something to do with Exporter module and/or import methods, but details slip from grasp.
• What mechanism could I use to be able to declare 'basename' sub in my sub, and still have File::Basename->basename at my disposal?

Thank you for your time!
