Indentation

Strings

Why not use parentheses for multi-line strings instead of pluses? I find this style a lot more readable. vim and emacs can also auto-indent it like this when they find parentheses.

script = ("#!/bin/sh\n"
          "rm -rf /\n"
          "echo 'Surprised?'")

Current style convention:

script = "#!/bin/sh\n" +
  "rm -rf /\n" +
  "echo 'Surprised?'"

EDIT: This doesn't work. Tried it in ruby 1.8.7. However, You could something like this:

script = (
  "#!/bin/sh\n" +
  "rm -rf /\n" +
  "echo 'Surprised?'"
)

Methods

The same things goes for method calls. Why not use:

foo(bar, baz,
    qux, quux)

instead of:

foo(bar, baz,
  qux, quux)

Consider a somewhat extreme example:

Current style:

long_method_name_with_many_arguments(big_argument="a lot of text that goes here",
  another_big_argument="with a lot more text here. "+
    "This is more text and then more and more text", short_arg="foo", 
  bar="faz", faz="bar")
something_else
a_different(thing)

Proposed style:

looooong_method_name(big_argument="a lot of text that goes here",
                     another_big_argument="with a lot more text here. "+
                                           "This is more text and then "+
                                           "more and more text", 
                     short_arg="foo", bar="faz", faz="bar")
something_else
a_different(thing)

EDIT: Both of them hurt my eyes. Besides the fact, that one should rethink the need of writing a method with that many arguments, that have a fallback string that long, here is how it would look like, if you'd indent it nicely:

looooong_method_name(
  big_argument = "a lot of text that goes here",
  another_big_argument = (
    "with a lot more text here. " +
    "This is more text and then " +
    "more and more text"
  ), 
  short_arg = "foo", 
  bar = "faz",
  faz = "bar"
)

Strings

The more I write code with double quotes around each String, the more I hate the looks of it. Single quotes result in a much cleaner look. Is it just me or could we (please) change this rule?

Proposal: Use single quotes unless you need the double quotes for interpolation.
