Code review comment for lp:~widelands-dev/widelands/bug-1675179-lua-hide-fields

Good idea about the enum class and the variable name, I will change that :)

I don't think that we will have desyncs here though:

- It's an additional option to an already existing function, so we should have seen desyncs before if this was a problem
- It only affects the current player, other players' and critters' states shouldn't care about what I see
- We would have functions like Bob::set_position and Building:set_seeing trigger a playercommand down the line just for their current vision - all their state changes should have been handled already at that point

Feel free to convince me otherwise, I'm not that familiar with all the networking stuff.
