Head Const is what C++ has for const, i.e. it is not
transitive, applies to one level only. D has transitive const.
What head const will do for us:
1. make it easy to interface to C++ code that uses const, as
currently it is not very practical to do so, you have to resort
to pragma(mangle)
2. supports single assignment style of programming, even if the
data is otherwise mutable
The downside is, of course, language complexity.
so keep const as it is and add headconst?
