Huh? You mean with string literals? That would be a rather silly 
reason to avoid `char[]`. Please show an example of .dup you'd 
like to avoid.

Are you saying that `string[]` is simpler than `char[][]`? That's 
not true: `string` is an alias for `immutable(char)[]`, so 
`string[]` is the same as `immutable(char)[][]`.

Before jumping to a solution, please elaborate on the perceived 
problem. I have a feeling that there is none.
