I want to double-check that it is correct to use "our" to import globals.
#!/usr/bin/perl -w
use strict;
BEGIN {
our $foo = 'foo';
}
sub something {
our $foo;
our $bar;
...at this point I can see 'foo' and 'bar' values.
}
END {
our $bar = 'bar';
}
If I do *not* import with "our $foo;" inside main::something(); I get
the following errors:
Variable "$foo" is not imported at ./script.pl line xx
Variable "$bar" is not imported at ./script.pl line yy
Global symbol "$foo" requires explicit package name at ./script.pl line xx.
Global symbol "$bar requires explicit package name at ./script.pl line yy.
Is this the correct way to import globals?
$perldoc vars
says...:
NOTE: For variables in the current package, the functionality provided by this
pragma has been superseded by "our" declarations, available in
Perl v5.6.0 or
later. See "our" in perlfunc.
