No, I meant languages which are not able to give me bit level control 
over a type and have to circumvent this restriction with either 
awkward "macro magic" or even can't do nothing at all.

If I mean to set the write buffer water mark of the SDRAM controller 
register, I'd rather write:

|SDRAM_Buffer_Control.WB_Watermark := Sixteen;

instead of

|SDRAMBufferControl := (SDRAMBufferControl and not WB_WATERMARK_MASK) or
|                      WB_WATER_MARK_16;

Not even to think of the much more cryptic C version.
