in thread One line assigment statement with regex match

I get search pattern not terminated when I try this: 
 my $re = qr/(?:${\(
                 join "|", map { qr/\Q$_\E/ } @terms
              )})/;

    Terribly sorry, I didn't test it.

    Yes, the double use of "/" to delimit regular expressions is tripping up the parser. Much better to use braces; 

    @terms=qw(foo bar b.*az);
my $re = qr{(?:${\(
                 join "|", map { qr{\Q$_\E} } @terms
              )})};
print "$re\n";

    The above will print "(?-xism:(?:(?-xism:foo)|(?-xism:bar)|(?-xism:b\.\*az)))" 

    $h=$ENV{HOME};my@q=split/\n\n/,`cat $h/.quotes`;$s="$h/."
."signature";$t=`cat $s`;print$t,"\n",$q[rand($#q)],"\n";
