Boost.Parser not usable with MSVC 17.10

Unfortunately, due to a bug in MSVC, Boost.Parser is not usable with MSVC 17.10.

The error message is:
```

1> To work around this problem, try simplifying or changing the program near the locations listed above.
1> If possible please provide a repro here: https://developercommunity.visualstudio.com

```

The problem is reported to Microsoft and fixed in newer versions of MSVC.

Unfortunately, poor me has to use MSVC 17.10 for reasons. So I'll invest some time to circumvent this MSVC bug.
If anyone knows anything about the problem that could help me, I'd appreciate if you shared your insights. The issue arises somewhere inside of `seq_parser::make_temp_result()`
