I'm making anagrams. According to the nextPermutation() docs, I need

I've tried .byCodeUnit. , .representation. I've tried sorting on the
dchar. I've tried sorting the on string.
The closest I've gotten:
string word = "bar";
string line2 = toLower!(string)(word);
dchar[] line3 = sort(line2.to!(dchar[]));
dchar[] line3 = sort(line2.to!dchar[]).release;
https://dlang.org/phobos/std_range.html#.SortedRange.release
"Error: cannot implicitly convert expression sort(to(line2)) of type
SortedRange!(dchar[], "a < b") to dchar[]"
import std;
void main()
{
string word = "bar";
dchar[] line3 = word.dup // make a copy to get a range of mutable
elements
.map!"dchar(a)" // convert char to dchar
Don't do this, use to!(dchar[]) as you have above. This will create
incorrect dchars for non-ascii text.
