in thread How can you split inside pop?

The +() syntax is often confusing. Try either of the following: 
my $x = "this is a string";
my $y = (split ' ', $x)[-1];
print "$y\n";

######## OR ########

my $x = "this is a string";
print( (split ' ', $x)[-1], $/);

That way, you avoid the scalar-context hack that is +().

    Ummm, to whom? Those who don't know about it? Also, that's not scalar context. Don't believe me?

    # perl -wl
$,=$";
print +(split " ","this is a string")[-1,1],"good";
__END__
string is good

    Yes. It's still the print LIST that we've all grown to know and love. I don't agree with your dislike of +() and I would tend not to refer to it as a hack. The only thing that the + does is disambiguate what the parentheses mean when perl attempts to parse it.
