Yes, you're using some internal knowledge. You cannot assume it works on 
any other platform or architecture. In theory, the D compiler could 
choose to change the ABI for passing D arrays and this would break. If 
fact, the ABI documentation [1] doesn't mention how a D array is passed. 
A different compiler could choose to pass it differently.
