That's not an "equiv of". It's "completely missing the point of". Each
"using" costs one new scope and one level of indentation which makes it

class when try/catch/finally showed with extensive examples just how
expensive extra indentation is.
Oh. Is that the only thing that bothers you about it?
That doesn't bother me much since it's basically for things you only
want to hold on to for a short span. You should either do your
business in a few lines of code and get out of there, or if you can't
then make it a function. Anyway, if the indentation bugs you, you
can always set emacs up not to indent on "using" blocks.
It's huge! In TDPL, as soon as I show the expansion of two scope(exit)
statements, code became unreadable. No wonder today's software has so
crappy error handling and state leaks: languages seem to make it as hard
as possible to write correct transactional code.
