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.
