Array Indexing

[DigitalMars D compiler News]

I have another problem (I'm kinda a newbie in D, I come from a .NET 
background) when I index an array with a byte. I have this function that 
returns a byte I use for index on an array. The thing is that whan that byte 
value is over 0x7F where it would be negative if it was a char the runtime 
raises an array bounds exception, I know a workaround and that is to and the 
value with 0xFF but I shouldn't have to (and if I perform an explicit cast 
it doesn't help it) since it is already a byte. Anyone knows if this is 
correct behavior?
