And here's yer "single-hyphen" toggle:

g@crash:~/tmp$ cat test.rb
def q; yield end

puts 1
%q{
  puts 2
  %q{
    puts 3
  }
  puts 4
}
puts 5
g@crash:~/tmp$ ruby test.rb
1
5
g@crash:~/tmp$ cat test.rb
def q; yield end

puts 1
q{
  puts 2
  %q{
    puts 3
  }
  puts 4
}
puts 5
g@crash:~/tmp$ ruby test.rb
1
2
4
5
