Should we explicitly state that a class field is optional?

[lua-rocks]

At the moment the language server doesn't do strict checks on class fields for nil. Whether you specify it as optional or not, the value of fields may be unset.

However, I believe that the information about whether it is necessary to check for nil before working with the field or not is important and we should explicitly indicate this.

Example:

---@class mt.PointedThing
---@field type string MUST EXIST
---@field under mt.Vector|nil CAN BE NIL
