I'm not quite sure if the .length property of a static array

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:

That would be nice, but a bigger problem I'm currently having, is
that you can not initialize fixed size arrays like this:
int[4] bla = [1,2,3,4];
Without causing a allocation. The literal will be allocated on
the heap, then copied onto the stack, and then it will become
garbage.
