You can't use AA's in -betterC.
The implementation is not templated and is in druntime.
One way you can do it:
import std.range : chunks;
import std.algorithm : map;
import std.array : array;
import std.conv : text;
string[] split = "Hello D".chunks(2).map!(v => v.text).array;
writeln(split);
foreach(val; "Hello D".chunks(2)) {
writeln(val.text);
}
Storage classes like immutable/const/shared are not tied to any memory
management strategy. Nor does it dictate memory lifetime.
It only dictates how it can be interacted with when you have a reference
to it.
immutable isn't tied to lifetime semantics.
It only says that this memory will never be modified by anyone during
its lifetime.
Anyway, the real problem is with const. Both mutable and immutable
become it automatically.
