why should typeof(s ~ x) == char[] ?
x is a mutable array of mutable chars
s is a mutable array of immutable chars
If you append something mutable to something immutable, the resulting
type must be mutable, as some of the contents is mutable and could be
changed - if that can happen the result can't be immutable. To get
around this there's .idup I believe.
