| 2 | We could either implement simple chaining for variable maps, or |
|---|
| 3 | implement generic composition classes. The former was choosen, |
|---|
| 4 | mostly because of simplicity. |

| 5 | |
|---|
| 6 | There were two implementation approaches for multiple option |
|---|
| 7 | occurences in options_and_arguments. First is store them |
|---|
| 8 | separately. The advantage is that it's easy to obtain all |
|---|
| 9 | occurences before certain position on command line. The |
|---|
| 10 | disadvantage is that we cannot return a reference to |
|---|
| 11 | vector<vector<string> > in get_all_values. It was considered |
|---|
| 12 | that if support for position-dependent options is to be |
|---|
| 13 | added, then we're be mostly interested in occurences of |
|---|
| 14 | a single option that were before some point. That's possible |
|---|
| 15 | with vector<vector<string> > storage. |
