Trouble using "our" in Perl 5.005.03

freddo411 has asked for the wisdom of the Perl Monks concerning the following question:

Question: In what version of Perl is "our" introduced and supported?

Consider this code:


package Errors;
require Exporter;
use strict;

our @ISA        = qw(Exporter);
our @Export     = qw(   error,
                        ff_error,
                        HTMLErrorFormat,
                    );


# ... more stuff...
[download]

Which gives me this:

>perl -c Errors.pm
Bareword "our" not allowed while "strict subs" in use at Errors.pm lin
+e 14.
Array found where operator expected at Errors.pm line 14, at end of li
+ne
        (Do you need to predeclare our?)
syntax error at Errors.pm line 14, near "our @ISA       "
Global symbol "@ISA" requires explicit package name at Errors.pm line 
+14.
Bareword "our" not allowed while "strict subs" in use at Errors.pm lin
+e 15.
Array found where operator expected at Errors.pm line 15, at end of li
+ne
        (Do you need to predeclare our?)
Global symbol "@Export" requires explicit package name at Errors.pm li
+ne 15.

It was a reserved word in Perl 5.005.03, but it was implemented in Perl 5.6	[reply]

I'm not sure exactly when `our` was introduced, but you can `use vars;` instead to do the same thing. Example: `use vars qw(@ISA @Export); @ISA = qw(Exporter); @Export = qw( error, ff_error, HTMLErrorFormat, );` [download] `vars` is basically deprecated in favor of `our`, but it's still there if you need it. Update: Forgot to mention that you don't need those commas in your `qw()` statements. The idea behind `qw()` is that it splits the list on whitespace, not commas. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer Note: All code is untested, unless otherwise stated	[reply] [d/l] [select]

our works only in Perl 5.6.0+. Depending on what you need to do with it, you can try use vars instead. Or, even better, upgrade perl. ;-) Michele.	[reply]
