I'm unclear on the concept of 'our'. I have a module, package foo;, that several different programs use. I want foo to contain the definition of a constant scalar bar that programs using foo can reference.

foo.pm 

package foo;
our $bar = 42;
1;

[download]
pgm.pl 
#!/usr/bin/env perl
use 5.36;
use foo;
# 'our $bar'? 'our $foo::bar'? 'my $foo::bar'?
say $bar;

[download]
I've tried several variations on declaring $bar in pgm.pl (including not declaring it at all) without successfully referencing the value that was set in package foo.

Could some kind monk straighten me out? Is this even what 'our' is meant for?
