[cmake-developers] Roadmap to CMake 3.0

[Rolf Eike Beer]

> Potential changes motivating a major version number bump include:

One thing I was thinking about was to really have lists as lists internally. 
Once you touch a variable in a list way (e.g. set() with more than one 
argument or any of the list() commands) a std::vector<> would be internally 
created and maintained as long as no non-list command (e.g. set() with only 
one argument that does not contain semicolons) is used on that variable. That 
way all following list-style accesses would be much faster. And even 
semicolons in list elements would work that way.
