(This is a follow-up to the question How to prevent metacharacter interpolation.)

In case of quoting the variable with:

m/\Q$string\E/;
[download]

What happens if the string itself has \E in it?:

$string = "Author[p100-107]\E-book.{Publisher}+_What?";
m/\Q$string\E/;
[download]

Does that mean that everything after \E in the string will not be escaped anymore and starts interpolating?
