For Perl `=>` is just a comma, and empty lists `()` are ignored when flattening lists. `perl -e' @a=(1,2,(),(),3);print "@a"' 1 2 3` [download] Cheers Rolf	[reply] [d/l] [select]

Empty elements (lists) in a list collapse, e.g. `(1, (), 2, 3, (), (), 4)` is the same as `(1, 2, 3, 4)`.	[reply] [d/l] [select]
