const

[Jeff Louie]

Hmmm... I just tested and note that the MC++2.0 compiler will accept
const on a handle to a managed object so that the method cannot change
the state of the object. This implies that theoretically C# could also
implement const. const and RAII are useful idioms. C# has using, but
could it add const?

It could, but unless the CLR implemented it, it woudl be ineffective(MC++
gets away with it, I believe, mostly as something C++ developers expect,
even if it doesn't confer true safety). And then that brings up the whole
mess of old code.

There have been numerous discussions about it in the past, personally I
think const is a bad way of solving the problem.
