I am coming back to perl after a long time.

The sample code these days also uses variable attribute my as:

my $inst = Extutils::Installed->new();
my @modules = $inst->modules();

Can any demistify 'my' for me??

"my" declares a variable that exists within the current scope and is
unreachable from outside the scope. So a "my" declaration in one package
cannot be reached from another package. "our" is identical to "my" except
that you *can* reach that variable from other packages. A "my" declaration
inside of a function just limits the scope and lifetime of the variable to
that function.

I just wanted to point out that to take full advantage of "my" you
might want to program using "use strict" also.
