Whoops.



puts "hello\nworld"
p "hello\nworld"

--output:--
hello
world
"hello\nworld"


def show_match(str,re)
  if str =~ re
    "#{$`}<<#{$&}>>#{$'}"
  else
    "no match"
  end
end


p show_match("hello\nhello", /llo$/)
p show_match("hello\nhello", /llo\z/x)

--output:--
"he<<llo>>\nhello"
"hello\nhe<<llo>>"
