func FindSpellingInconsistencies

func FindSpellingInconsistencies(ids []string) [][]string

FindSpellingInconsistencies finds spelling inconsistencies in identifiers. The identifiers are considered to be the same if they are spelled the same when expressed in UpperCamelCase. For example, `left_paren` and `LeftParen` are spelled the same in UpperCamelCase. Thus they are considere to be spelling inconsistency.
