Then the operations downstream will not produce any results.
For example, the array will be empty below:
import std.stdio;
import std.range;
import std.algorithm;
import std.string;
import std.functional;
void main() {
auto significantLines = stdin
.byLineCopy
.map!strip
.filter!(not!empty)
.filter!(line => line.front != '#')
.array;
if (significantLines.empty) {
writeln("There were no significant lines.");
} else {
writefln!"The lines: %-(\n%s%)"(significantLines);
}
}

And there it is!
I was missing
```d
.filter!(not!empty)
```
My code now works exactly how I wanted. Thanks!
