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,
