There's a small issue in your ternary operator, if 'cstr' is non-const
but null, you will end up returning an immutable rather than a mutable
string. In fact your return type will always be const because of this
ternary (mutable and immutable both implicitly convert to const). I
suggest changing it to this:

return cstr ? cstr[0 .. strlen(cstr)] : cstr[0 .. 0];

You can also use inout(char)[] on the return type, it documents the
function better (and this is how I caught the ternary issue as well).
