( #3333=superdoc: print w/replies, xml ) Need Help??
This reduces the degrees of freedom of the ^ $ . operators
Maybe that hints at the following inconsistency I see with the "the end of the line (or before newline at the end)" rule?

Example

print('String: a\nb\nc\n' . "\n"); $text_1 = "a\nb\nc\n"; $text_1 =~ s@(\n)$@@s; print("----------\n>" . $1 . "<\n"); print("----------\n>" . $text_1 . "<\n");
Gives:
String: a\nb\nc\n ---------- > < ---------- >a b c<
In this case, the $ behaved like \z. Or another way to say it, in this case explicit \n matches where dot with s mod doesn't.
