My question was inspiried by const/final/invariant discussion. But my  
question is not about necessarity of adding const/final/invariant. So let  
take me some explanation.

At first, I'm C++ programmer and I like 'const' in C++. Sometimes it  
really helps to avoid bug (last case was a few days ago). Because of that  
I want to see consts in D (but current situation with  
const/final/invariant looks too complicated for me).

But the question isn't in const or AST macros or something else. The  
question is in incompatible changes to language after the short time since  
v.1.000. It is not good I think.

I think it always be something cool and desirable for including in  
language. Even if we don't know now what it will be. For example: why  
thought about const/final/invariant at Jan 2007 when v.1.000 was released?

Because of that must be some moment when Walter say: "We stop adding new  
features. Now we take two or three years of language stability and see  
what happens here". I thought v.1.014 is a good moment for that. But now  
we are talking about consts...

So my question is: "Is there a planed time-out in D evolution?"
