digitalmars.D - Re: Signed word lengths and indexes

 1) I'd like D to use signed words to represent lengths and array indexes.

This would lead to silent breakage of code transferred from C and C++.

I actually wrote an application in C and used signeds for array indexes, string positions and field offsets.
 2. For an operating system kernel's memory management logic, it still would
make 
 sense to represent the address space as a flat range from 0..n, not one that's 
 split in the middle, half of which is accessed with negative offsets. D is 
 supposed to support OS development.
 

Not to mention that if you really need it, you *can* workaround compiler checks by declaring your own getters/ranges.
