There are two very different use cases in D here.
An option is to add another kind of switch attribute:
enum switch (foo) {
case c1: break;

We already have an enum switch - it's called final switch.
The purpose of this idea is different. A final switch requires to list all

Personally, I think that simplest and best solution is to just restrict case
statements to compile-time constants like every language does. I agree with Don

`if (x = foo())` can't work, so I don't know why `switch (x = foo())` can.
That's easy. With if, there's a strong possibility that the programmer really

What would it be anyway - just an optional check for the programmer
similar to the override attribute?
override will stop being

This wouldn't make sense - why should I be forced to add something just to
show
I know that all the case values are compile-time constants?

Some argumentation in favor of a dynamic switch
switch (receive(ch0, ch1, ch2))
{
case ch0:
writeln(ch0.get());
break;
case ch1:
writeln(ch1.get());
break;

I don't understand why anyone sees the need to limit the switch construct in

Well, it works with variables which are of type int. TDPL claims that it works
with variables, and switch statements work with integral types and strings. So,
