I had always thought that `::' is "cast, no matter how", and date() is "call the function date, which happens to do the conversion". But now it seems that the supposed "cast" syntax is really just a dumb function call whereas the function syntax actually does more intelligent work behind the scenes. I have a feeling these type conversion issues aren't going away for a long time... -- Peter Eisentraut Sernanders väg 10:115 peter_e@gmx.net 75262 Uppsala http://yi.org/peter-e/ Sweden
