Because you could write a more elegant code. If you return "self" even in methods that don't need to specify a return, you can codify using a style more declarative instead of a procedural style. Instead of this: --- obj.exec; obj.foo; obj.bar; --- We can do this: --- obj.exec.foo.bar; --- Looks nothing, but imagine that you give a instance from another object. If these methods (exec, foo, and bar) do not return "self", you need to declarate a variable — or use "with". So: --- obj := x.getAnObject; obj.exec; obj.foo; obj.bar; --- But if you return "self": --- x.getAnObject .exec .foo .bar; --- Best regards, Marcos Douglas ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ mseide-msegui-talk mailing list mseide-msegui-talk@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mseide-msegui-talk
