  One signature for use is "use Module VERSION"
  
  You can use an expression for VERSION, even though the manual isn't crystal clear on that. A little testing goes a long way.
  
  print returns 1 on success, so you're trying to use that module with version 1 or more.

    That makes sense. Now that I think about it, I don't know how I didn't get it at first...
    
    But come to think about it again, what about CPAN::Mini (version 0.20) and strict?
    
    Wait... strict was giving a different error...
    
    I need to get some sleep... over and out, back again sometime tomorrow... :-)

  It all depends on the &import of a module.

  Lingua::Identify [cpan.org] uses Exporter [cpan.org] which considers the parameter a version number and croaks because it's higher than the module's.

  strict [cpan.org] uses a custom importer which considers the number a non-existant pragma tag and croaks.

  In case noone else defines an &import, modules inherit &UNIVERSAL::import. Interestingly, that one does differentiate between a literal number and an expression:

  $ echo 'package Foo; our $VERSION = 0.1; 1;' > Foo.pm
  $ perl -le

  You need a semi colon after the use statement.
  Without that you only have one statement:
  
  #!/usr/bin/perl
use strict   print "Hello World\n"
  
  The return of the print statement is 1 (unless it fails).
  This effectively changes it into use strict 1.0 , whereby the module is required to be at least version 1.0
  
  Of course your code should look like this:
  
  #!/usr/bin/perl
use strict;
print "Hello World\n";

    That was the precise point, the fact that the code would work some of the times without the semicolon :-)

    The part of the version one was taken care of pretty quickly [perl.org], but it took Aristotle [perl.org] to find out the reason for the exceptions [perl.org] (that is, modules below version 1 working and vice-versa).

    You wouldn't believe how ashamed of myself I am for not having solved the problem before posting it... oh well, one learns new things everyday :-)

    Anyway, if that's what it takes to bring a new user [perl.org] to the site, you ca
