I think nested foreach loops are more readable.

Use whatever fits your style best or what you are most familar
with. But be aware that there's a concise alternative:
```d
import std;
void main()
{
import std.ascii; // because there's also std.uni.isLower
"Book.".filter!isLower.each!writeln;
}
```
or alternatively with fully-qualified naming:
```d
import std;
void main()
{
"Book.".filter!(std.ascii.isLower).each!writeln;
}
```
