In some cases, code may include sequences of literals that represent lists or tables of constants, such as lookup tables. Large sequences of these (particularly parts with many zeroes) will be identified by CPD as duplicates, but in practice, these are not the types of duplicates that are considered interesting. This introduces a new option for CPD (--ignore-literal-sequences) that ignores these sequences of literals, in a very similar way to how using directives for C# can already be skipped as well. For now, this functionality is restricted to C#, but it could be added for other languages as well.
