I'm not sure what you mean by "multiple namespaces". Could you
elaborate?
Also, I'm prompted to ask exactly what is the code of Class::new()
What *exactly* is the object? Has it been bless()'d?

Modules I've done; require's I'm a little green on. =o)
Doesn't require pull the code into the current namespace?
Anyone?

Well, (people, check me on this) I believe a pragma is a module, like
strict.pm, while use is a function (c.f. perldoc -f use).
use myMod 'foo';
is functionally the equivalent to
BEGIN { require myMod; myMod::import('myMod','foo'); }
The main difference is (I think) that modules use the package statement
to declare their own namespaces, and the use statement implies a call
to that namespace's import() function.

I'd have to see it.

A bless()'d object knows where to look.

That again makes me ask -- is it bless()'d?

You can always access a global variable (or create one, for that
matter) by specifying the namespace.
$main::x = 1; # satisfies strict that you know what you're doing
The common practice for objects is to use a hash reference as made by
{} (though I've seen objects that were actually references to constant
numbers, or closures....), and for a class object, it needs to be
bless()'d into that class. A common constructor:
sub new {
my $class = ref($_[0]) || $_[0] || 'SomeDefault';
bless {}, $class;
}
Does your code do that?
Forgive me if I'm off track, here....
