Failures:

  1) PrivacyFilter does not filter invalid emails
     Failure/Error: filter(text_with_invalid_emails).should eq text_with_invalid_emails
       
       expected: "Contact me here: _invalid@email.com"
            got: "Contact me here: _[EMAIL]"
       
       (compared using ==)

  2) PrivacyFilter does not filter invalid phone numbers
     Failure/Error: filter(text).should eq filtered

     # ./lib/homework/run_with_timeout.rb:5:in `block (2 levels) in <top (required)>'

  3) Validations can validate more complex phone numbers
     Failure/Error: Validations.phone?(phone).should be(valid)
       
       expected #<FalseClass:0> => false
            got #<TrueClass:2> => true
       
       Compared using equal?, which compares object identity,
       but expected and actual are not the same object. Use
       'actual.should eq(expected)' if you don't care about
       object identity in this example.
