in thread Creating an index on a string-collection

Hey, reverse() on a scalar doesn't reverse it! I wonder why I thought it did. Fixed code will go in the original node in a moment. I'm sure there are other bugs though - this was just example code!

    It does in  scalar context: 
    >perl -wMstrict -le
"my $s = 'foobar';
 print reverse $s, 'zot';
 print scalar reverse $s, 'zot';
"
zotfoobar
