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.
