Apparently \Q still does variable substitution. But this seems to work:
echo '[email protected]' | perl -ne "\$a='[email protected]';/\\Q\$a\\E/ and print"
echo '[email protected]' | perl -ne "\$a='"{}"';/\\Q\$a\\E/ and print"
It it starting to be as ugly as the sed command, but it might just be
more portable: We avoid having to deal with different odd dialects of
sed.
