Anyway, no one's saying C# is flawless. Personally, I would love the ability to declare immutable graph references.
I fail to see how it is an "obvious critical flaw" :)
You have to create a separate overload that takes an Action instead of a Func,
and has an identical implementation except for omitting the return keyword.
Granted, that’s not much work for a simple helper like the above,
but what if it were more complicated?
Eg. this would do the trick without repeating the implementation: http://pastie.org/8628864
Just two one-line overloads as entry points.
The problem is that void can't be used as a regular type identifier.
In a lot of langages (like Python, Haskell, F#, ...) there is a regular type for void. This type is often implemented as such :
sealed struct Void {
}
As the compiler is smart enough to see there is only one kind of Void value, it can be entierly removed from the generated code and thus doesn't make your code slower.
