Hm. Can you give an example? (A web link, maybe to a paper or some, such
would be enough).

I am asking because I am used to calculating with infinity from integration
theory where the rationale is similar: formulation of most of the basic
theorems would loose a lot of its elegance if the 'infinite case' had to be
handled explicitly.
