1. Fix index, including both start and end. So Literal[start:end+1] will be a valid part. 2. Replace any with string, add file param type 3. Start of making the evaluator, starting with regexp for param types (these expression can be changed or/and overriden by user later on) Former-commit-id: ab95265f953dadbf84170b543e1ff8840f9c4a14
