If it's acceptable for you, the following code calls .save on
the elements and it works:
import std.algorithm.iteration;
import std.stdio;
import std.array; // <-- ADDED
void main()
{
immutable(string[])[] icycles;
icycles ~= ["one", "two"];
icycles ~= ["three", "four"];
foreach (number; icycles.map!(r => r.save).joiner)
writeln(number);
}
Again, .save on an array is cheap. What will happen is that the
original immutable arrays will be untouched but their proxies
returned by .save will be consumed.
Great, thanks. I didn't even know about save... Its documentation
is hidden quite well, because I still cannot find it. Seems it is
about time I read the books.
