Is the following compiler behavior consistent with language

x ~= 4;

writeln(a);

I understand why thw program could output [1,2,3] (like in C++
without &) or [0,2,3,4] (python, C++ ref). But [0,2,3]? It was
unpleasant surprise.
The behavior of D's slices is often unintuitive. To understand
them, read this article: http://dlang.org/d-array-article.html
