A paper I've recently read:
"Verifiable Functional Purity in Java", by Matthew Finifter, Adrian Mettler,
Naveen Sastry and David Wagner:
http://www.cs.berkeley.edu/~finifter/pure-ccs08.pdf
At page 12 it says some things about D2 too (this article is not updated to the
last changes in D2):

class or instance immutability is necessary to ensure determinism in a
concurrent program, as otherwise a mutable alias can be used to
concurrently modify the object.
That's the price of being a systems language - it is possible to subvert
the type system. However, we also h

It's similar, of couse. I think there is no 'pure' tag, the compiler infers if
a method is pure on the base of its arguments. In D even a function that is
technically pure is not seen as pure of you don't tag it w

Having the compiler determine purity would be cool, but it runs into a few of
problems.
The most serious one I can think of is:
Suppose you are depending on a function being pure. If the compiler determines
its purity, it *does not tell you* if it is impure. Your code

Just to be sure: in my original post of this thread I have not asked to change
