Regarding foreach loop index ranges

[bearophile via Digitalmars-d-learn]

In this case I am not sure about bug reports, so I ask here.

In this program the first loop doesn't compile, giving a nice 
error:

test.d(3,5): Error: index type 'ubyte' cannot cover index range 
0..300

If you comment out the first loop, the second compiles and runs, 
but it seems to go in an infinite loop:


void main() {
     int[300] data;
     foreach (ubyte i, x; data)   {} // Error
     foreach (ubyte i, x; data[]) {} // compiles
}


For the second loop one possible alternative behavour is to 
refuse a ubyte index and accept only a size_t index if it loops 
on a dynamic array.
Another alternative is: the i variable can go from 0 to 255, then 
go up to the modulus of the remaining indexes, and then stop.

What do you think?
