Personally, I've always used .init whenever I had to guarantee a valid array,
even if it was empty.

# int[] arr = int[].init;

It gets a little sticky with compound array types, as the compiler doesn't like
this syntax:

# char[][char[]] dictionary = char[][char[]].init;

So I wind up having to use parentheses or an alias to tighten it up:

# char[][char[]] dictionary = (char[][char[]]).init;

# alias char[][char[]] Dictionary;
# Dictionary dictionary = Dictionary.init;
