On other issue someone from Intel staff told they can't comment on Intel's future plans. This is indeed okay due to marketing, I guess.
On other issue someone from Intel staff told to fully implement C++11 is the fairly main goal of Intel.
But my question is, will "constexpr" be implemented in near future (i.e. ICC 13.x series) or will I need to wait for the long time (i.e. in ICC 14.x series maybe?)?
If you cannot comment on future plans even on my last rather abstract question, I will accept it. But I am so impatient, believe me. I guess I am not the only-one.
