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,

Vietnam isn't an alternative because it needs help. It is an alternative because it can do things cheaper than PRC can.
