[ruby-talk:11008] Re: Ruby/Tk, what am I doing wrong... [long answer]

This, nesting blocks, was the cause of my confusion with grid also (see
02/14/2001 thread). Nested blocks keep putting the widgets top-to-bottom
rather than the grid pattern I was specifying.

I now notice that the pickaxe book uses parenthesis  for all of its examples
(Ruby Tk Chapter) except for the first very basic example.

Has anyone supplied a definitive answer to this question?
