How very true.  It's very cool.
Before reading this thread, I did not know that we can write in 1.9:

> puts object
> .methods

I love the style too.


Even if I look at the situation objectively, comma may (or should) be
able to be put in a next line, as long as dot is able.



$ ./ruby -e '
x = { 1 => "1"
    , 2 => "2"
    , 3 => "3"
    }
p x[3]
'
"3"

$ ./ruby -e '
def foo(*r)
  p r.join(", ")
end

foo( "foo"
   , "bar"
   , "baz"
   )
'
"foo, bar, baz"
