It is the secret "eskimo greeting" operator.
This might reveal what is happening:
perl5 -MO=Deparse -pe ' } { $_="foo\n"' /dev/null
LINE: while (defined($_ = <ARGV>)) {
;
}
{
$_ = "foo\n";
}
continue {
print $_;
}
-e syntax OK

Subject: What does "}{" mean?
What does the construct "}{" mean? As in
$ perl -pe ' } { $_="foo\n"' /dev/null
foo
I figure it has to do with how the -p switch affects the script that
is passed to the interpreter. Is this documented anywhere?
