in reply to i thought i knew 'our'...

Update: from the man pages i get: An `our' declares the listed variables to be valid globals within the enclosing block, file, or `eval'.
That is, it has the same scoping rules as a "my" declaration, but does not create a local variable.

    'our' and 'my' are two very different beasts. You can not substitute 'our' with 'my' or vice versa, take this as an example: 
    use strict;
{
   our $y;
   $y = 17;
   print "Inner: $y\n";
}

our $y;
print "Outer: $y\n";

    That will print:
    Inner: 17
    Outer: 17
    Now, if you substituted our with my (s/our/my/g) then it would print:
    Inner: 17
    Outer:
    ...and it would complain about use of uninitialized variable :-)

      you are right, what i meant was that our could be use to declare variables in the begining
      of a program like: 
      #!/usr/bin/perl -w
use strict;
our($foo,@bar,%args); <- this was what i meant.

      Not to s/my/our/; as you pointed out. Sorry didn't explain myself quite right.
