I am old and frumpy and still prefer to do it the "old fashioned way" and not use the fancy dancy built in perl vars.

I would do it this way:

Code:
my $lineNumber = 1;

while ($ln = <>) {
  print "$lineNumber: $ln\n";
  $lineNumber++;
};

Yeah, I know it doesn't make full use of the plethora of built in Perl vars, but most any programmer can sit down and look at it and go "Ah-ha!"

Learing Perl is a good thing. I use it under Win32 at work and under *BSD at home.

Perl::Critic::Policy::TestingAndDebugging::ProhibitNoStrUser3Contributed Perl DocumePerl::Critic::Policy::TestingAndDebugging::ProhibitNoStrict(3)

NAME

       Perl::Critic::Policy::TestingAndDebugging::ProhibitNoStrict - Prohibit various flavors of "no strict".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       There are good reasons for disabling certain kinds of strictures, But if you were wise enough to "use strict" in the first place, then it
       doesn't make sense to disable it completely.  By default, any "no strict" statement will violate this policy.  However, you can configure
       this Policy to allow certain types of strictures to be disabled (See "CONFIGURATION").  A bare "no strict" statement will always raise a
       violation.

CONFIGURATION

       The permitted strictures can be configured via the "allow" option.  The value is a list of whitespace-delimited stricture types that you
       want to permit.	These can be "vars", "subs" and/or "refs".  An example of this customization:

	   [TestingAndDebugging::ProhibitNoStrict]
	   allow = vars subs refs
