Ok, but lots of people have been talking about const correctness for 
years (including yourself), stemming from the known C++ problems, and I 
don't see how "transitive immutability" (a deep const) is a new idea 
that nobody asked for. The only thing new here is that you guys came up 
with an implementation for D, and lots of people were glad to have it, 
even if many were also against it.
