So, wait, if I have a program like this:
void appendSailor (string s) {
s ~= "Sailor";
}
void main () {
auto s = "Hello World!";
appendSailor(s[0 .. 6]);
writefln(s);
}
I should expect to get "Hello Sailor" as output? Or is it just that a new array
of characters will be allocated and that will be appended into, so
`appendSailor()` becomes a slightly expensive no-op?
The former behavior would be really horrible, while the latter behavior doesn't
seem to provide an overwhelming advantage over not allowing append-in-place for
arrays.
