Thank you D for not having "mutable" as in C++. I don't see 
mutable often in C++ and is one of those corners in C++ that I 
don't think make much sense.

const is const, easy. In C++ const might not be ROMable. In D 
immutable is ROMable and transistive const helps this (unless 
there is some escape hatch I don't know about).
