in reply to default values for lists

Hi pike,

You could try using the trinary operator...

@d = @a ? @a : @c;

In the example given, if @a returns true (in scalar context ie. has a nonzero length) then it is copied into @d, otherwise the contents of @c are copied into @d.

Update: Arrgh, fglock beat me to it!
