Quoting is not an identity function in Perl. Don't treat it like one or you'll eventually get bitten.

Make a proper identity function instead (simplified to only return the first arg instead of all of them):

sub ident { shift }

bless \(ident($_)) => 'Foo' for 3;

A little more typing? Yes. Avoids subtle bugs? Yes :)

    That's the point of \"$_", isn't?

      Right. People expect "$_" to return the same data (i.e., an identity function). But that's not strictly true in Perl, due to the way Perl does implicit conversions.
