[dmd-internals] Implementation change without matching spec change

Of course you have a great point. The trouble is, for me anyway, it's hard to 
write the spec incrementally. It also tends to make for a crummy spec. I find it 
easier and works better to take a more holistic view of spec updates.

For example, I am currently working on the list of issues tagged with 'safe'. 
Many of them interact with each other. It's easier to work on them more or less 
in parallel when I have the 'context' of how that part of the code works in my 
head. The same goes for spec updates.

But I don't want it overlooked, hence the shortcomings should all have bugzilla
