In general, the answers you've been getting are along the lines of "you
can't do that" or "that isn't the Ruby way" and, strictly speaking, both
are accurate. That said, there's sort of a way to do it for methods, at
least:

class << Object
  alias defm define_method
end

class Foo
  defm(:bar) { |baz|
    puts baz
  }
end

x = Foo.new
x.bar('Whee!')

So, yeah, it isn't perfect, but if you *really* want that C syntax feel,
that's about as close as you're going to get.
