Header generation in 1.014 and beyond generates "ref" where "inout" was 
generated previously.  That caused problems for a while.  Also, I 
suppose it's worth mentioning that 1.015 and beyond have TypeInfo for 
"const" and "invariant", which suggests that either some of the const 
features are in D 1.0, or the addition was a mistake.  These classes 
weren't added to Tango, but they are in Phobos.

It does to me.
