I get an compile time error with sort after using toLower,
putting in array before sort, didn’t work:

.map!(std.uni.toLower)

It works for me. Modifying your code to
```
void main() {
import std;
"EzraTezla"
.to!(char[])
.byCodeUnit
.map!(std.uni.toLower)
.array
.sort!"a<b"
.writeln;
}
```
compiles and gives the expected output.

```d
void main() {
import std;
"EzraTezla"
.to!(char[])
.byCodeUnit
.map!(std.ascii.toLower)
.array
.sort!"a<b"
.writeln;
}
```
std.uni.toLower works, but not ascii. Ascii works with bycode
after map, though.
