Re: brian's Guide to Solving Any Perl Problem (perl version too old?)

Not sure if your perl version is too old?

$ perlver foo.pl


   --------------------------------------
 | file   | explicit | syntax  | external |
 | -------------------------------------- |
 | foo.pl | ~        | v5.10.0 | n/a      |
 | -------------------------------------- |
 | Minimum explicit version : ~                             |
 | Minimum syntax version   : v5.10.0                       |
 | Minimum version of perl  : v5.10.0                       |
   --------------------------------------

$ perlver --blame foo.pl

 ------------------------------------------------------------
 File    : foo.pl
 Line    : 3
 Char    : 17
 Rule    : _perl_5010_operators
 Version : 5.010
 ------------------------------------------------------------
 ~~
 ------------------------------------------------------------

$ cat foo.pl
my $foo = 6;
my @bar = ( 3,6, 9 );
print 1 if $foo ~~ @bar;

Then you can add use v5.10.0; or use 5.010000; to your foo.pl, and perl will do the version check
