Generally with Ruby, methods with the '!' are destructive, and modify the
receiver in place:

s = "foobar\n" => "foobar\n"
s.chop => "foobar"
s => "foobar\n"
s.chop! => "foobar"
s

=> "foobar"

...here you can see 'chop' returns a modified copy, leaving 's' intact,
whilst 'chop!' modifies 's' directly.

HTH,
