I know this type of writing.
which is the best style

#!/usr/bin/perl -w

use strict;
use warnings;

my %Conf = (
XferMethod => "rsync",
XferLogLevel => "1",
RsyncShareName => "___1___",
ClientNameAlias => "___2___"
);

which is the best style

#!/usr/bin/perl -w

#!/usr/bin/perl


use strict;
use warnings;

Lexical warnings are better than the -w switch.

my %Conf = (
XferMethod => "rsync",
XferLogLevel => "1",
RsyncShareName => "___1___",
ClientNameAlias => "___2___"
);

my %Conf = (
XferMethod => 'rsync',
XferLogLevel => '1',
RsyncShareName => '___1___',
ClientNameAlias => '___2___'
);


Double quotes give you 2 things beyond what single quotes give you,
variable interpolation and backslash escapes.

It is misleading (ie. bad style) to use double quotes when you are
not making use of one of those two things.
