You're totally missing the point. Code like this is very prone to bugs:

int[5] x = [1,2,3,4,5];

because as soon as somebody edits the list of elements, the count will be
wrong. Restating something that the compiler already knows is a bad idea. (The
same problem occurs in C/C++; in the C case, depending on the compiler, you may
even get a gratuitous array overrun.)

The proposed int[$] = [ ... ]; is a very good solution, because $ already means
"length of array" in D, and would fit seamlessly into the existing language.
