Hello, everyone!
I like to work with arrays of strings like `string[] strArray`,

I do not like to work with arrays of strings such as `char[][]

Yeah, that would be neat. But typing out .dup isn't that
bad, and converting a `string[]` to a `char[][]` is simple:

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

`std.array.split` is eager. It may be faster if you

Sounds like the halting problem. So, no, generally this is not
possible.
