Yes, recently zero-length arrays were improved in DMD right to 
allow that better kind of usage in variable length structs. Past 
versions (visible in the Revision History in that Rosettacode 
site) used more awkward code, like:

(cast(CellIndex*)&state.c_)[i] = x;

because until recently the .ptr field of a zero length array was 
null. Recently this was fixed and now it's not null any more. It 
returns the start address. So you can use (you still need to use 
.ptr because the length is zero):

c_.ptr[i] = x;
