Return value from a scope

[rccarlson]

I've been learning F# and I've really enjoyed the scoped definitions available there. For example:

let sum =
  let a = 1
  let b = 2
  a + b

This would set sum to equal 3, while leaving a and b out of scope for any other code. I would love to have something like this for C#. My vision for this would be something like:

int sum = {
	int a = 1;
	int b = 2;
	return a + b;
};

This would have the same behavior as:

int sum = new Func<int>(()=>{
	int a = 1;
	int b = 2;
	return a + b;
}).Invoke();

This would be very helpful for cleaning up working variables (such as StringBuilders or iterators) and only holding on to the resulting value
