[dmd-beta] dmd 2.064 beta take 2

  struct S
  {
      immutable int c = 123; // I agree with Walter, what if this is far
away from the constructor
      this(int i) { c = i; }
  }

  struct S
  {
      immutable int c = 123; // This should be static, compiler issues error
      // No constructor
  }

would it be possible to disallow a default initializer for const /
immutable member variables and instead allow a single assignment from the
constructor?

That way you can supply the default in the constructors arguments, and
everyone can see exactly what is going on. In the cases where the
variable's value cannot be overridden you HAVE to use static with a default
initializer.
