Length of fixed size arrays

Currently it's always a compile-time constant.

But I have asked for some kind of Variable Length arrays 
allocated on the stack, as in C99, because using alloca() to 
create a 2D array on the stack is not good, it's noisy, unsafe 
and bug-prone. In this case their length is contained in some 
scoped variable or in an argument, at run-time.

They are discussing VLAs again for C++14:
