Something like Model.Items.SetMaxResults(20); In other words, I would like nHibernate to return IQueryable instead of a simple IList, when I access a collection.

• Lisp-style quotation in HTML

  - by InClj

  In Lisp, evaluating '(+ 1 2) produces '(+ 1 2), not 3. It seems that HTML doesn't support Lisp-style quotation so you can't say something like <quote><b>not bold</b</quote in HTML and let it just produce <b>not bold</b instead of not bold. Is there any technical reason or historical reason for that? Thanks.
