So do they all amount to the same thing? I can see that the 4th way
would allow you to pass arguments. When you read the docs for modules
they (all the one's I can recall) show either
my $inst = new Some::Module;
or
my $inst = Some::Module->new;
I thought there was some black art to allow you to make a constructor
work with the first example.
