Hi, Martín!
This is exactly my point, as I already replied to Hugo. I don't see so much value in with/endwith construction and it would cause more harm than good. Constructions such as "foreach" and "using", as you pointed out, are VERY useful, since they minimize the surface of error for the developers and put a level of abstraction over some Design Patterns. This is good. I don't see with/endwith on this category - but I obviously may be wrong.
