I have just started to delve into Perl, and going through the following example: 
#!/usr/bin/perl
use strict;
use warnings;

use Path::Class;

my $dir = dir('foo','bar'); # foo/bar

# Iterate over the content of foo/bar
while (my $file = $dir->next) {
    
    # See if it is a directory and skip
    next if $file->is_dir();
    
    # Print out the file name and path
    print $file->stringify . "\n";
}

[download]
Reading the code.... 
my $dir = dir ('test1');

[download]

# local scalar dir is assigned by dir ('test1')
the dir on the RHS, being possibly from Path::Class (CPAN)
while (This condition hold true)
# Simple While

my $file = $dir->next $dir scalar de-references the function next ? HOW ?
HOW do i guess that next would indeed be written as next and not next(), etc
since there is NO reference/example for "next" in
Class.pm Same goes for stringify, or is_dir()
Now in this case is_dir() seems again to be a function, but how come its called differently

Thanks,
