D2 is really that stable as it is claimed to be?

Enum members with no initializer are defined to be set to the previous enum 
member's value + 1. This, of course, can overflow if the previous value is the 
max value for the type. For example,

enum E {
     A = int.max,
     B
}

C:\cbx\mars>dmd test
test.d(3): Error: enum member test.E.B overflow of enum value cast(E)2147483647

This change was made because the behavior of ignoring the overflow was listed as 
a bug.

Since you said it was unclear, how could this be made clear?

------------------------------------
As C code:

enum E {
     A = 2147483647,
     B
};

and gcc reports:

test.c:4: error: overflow in enumeration values
