Hi Rodrigo,

thank you for answering.

But that' s my problem: One one web page I do not get all attributes I need
to instantiate the object correctly. Simple unrealistic example. One one page
the user can enter a "name" on the second the "age". The object can be instatiated
if you provide a valid name and age.

After the first page I do have the name, but not the age yet. But I can't instatiate
the object because it throws an exception because age is not valid, isn't it?
Or does Moose check constraints only on provided attributes. This can't be true
with "required" attributes, can it?

I would like it to do so...

I start to hate this perl slogan...  ;-)
I want a "good" way.

What do you mean with that?
