Thanks for the explanation, Eric. That helps clarify what's going on (i.e.
\Q parsing takes place before regex parsing).
However, can you elaborate what you mean by "if you have one (\Q..\E) in
your regular expression, it's an error"?
Isn't that the point of having \Q -- to provide quotemeta() in a regex?
You're not suggesting that this example from the quotemeta() docs is
improper?
my $sentence = 'The quick brown fox jumped over the lazy dog';
my $substring = 'quick.*?fox';
$sentence =~ s{\Q$substring\E}{big bad wolf};
I understand that as part of the parsing process, the \Q..\E no longer
remains part of the compiled regex and should not be considered as such.
Is this what you meant by this?
