Ahhhh, i am starting to see now:
- my declares a local variable which is not found in
a package's symbol table
- a local var does show up in the symbol table, but
if you use strict, then you have to fully qualify the
variable name (that is, prefix the package name)
- our handles the strict vs. non-fully qualified local
vars
perrin pointed me to CPAN and the
Devel::Symdump
module. Here is another snippet to help explain:
#!/usr/bin/perl
#use strict;
use Devel::Symdump;
my $obj = Devel::Symdump->new('Foo');
print map {"$_\n"} $obj->scalars;
package Foo;
local $Foo::qualified;
local $unqualified;
our $our;
my $my;
Which (without use strict) produces this ouput :
Foo::qualified
Foo::our
Foo::unqualified
If strict is turned on, then $unqualified will cause a
compliation error. I think i get it now! :)
Thank you tachyon, perrin, and also rob_au for
pointing out What is it adding to my symbol table?.
