Annoyance with new integer promotion deprecations

[H. S. Teoh via Digitalmars-d]

Code:

        struct S {
                byte[2] x;
        }
        void main() {
                S s, t;
                s.x = [ 1, -1 ];                // OK
                t.x = [ -s.x[0], -s.x[1] ];     // NG (line 7)
        }


Compiler says:
        /tmp/test.d(7): Deprecation: integral promotion not done for `-s.x[0]`, 
use '-transition=intpromote' switch or `-cast(int)(s.x[0])`
        /tmp/test.d(7): Deprecation: integral promotion not done for `-s.x[1]`, 
use '-transition=intpromote' switch or `-cast(int)(s.x[1])`


Why should I need to explicitly cast to int only to reassign it back to
byte?!  This is ridiculous.
