No, not exactly. Puppet's diagnostic is deceiving here: classes may be
declared any number of times, *BUT* only the first declaration evaluated
may have the resource-like form, e.g.
class { 'base::systemusers': }
This is and always has been an excellent reason to avoid using
resource-like declarations, of modules' public classes, though with care,
you may use them inside a module for that module's private classes.
Elsewhere, use include-like declarations instead:
include 'base::systemusers'
... and rely on automatic data binding for any needed parameter
customization.
However, classes are idempotent. Declaring the same class multiple times
(in one of the allowed ways) has the same effect as declaring it just
once. That is in fact one of the reasons why only the first-evaluated
declaration of a given class may take the resource-like form.

Yes, the OP appears to want a defined type here, not a class, because they
appear specifically to want non-idempotency. This goes straight to the
difference between classes and defined types.
