D's type system is not a right thing to care about.

Note, that the purpose of inout is to transmit qualifier from 
parameter to return type. Inout in constructors and void 
functions doesn't make much sense. And your code does not 
demonstrate necessity to make any of parameters as inout.

Yes, const cast.

The real answer is "no", because qualifiers do not work well with 
special functions(operator overloads, constructors, destructors, 
postblits).
