nodiscard for certain returned variables

[oeshennix]

Functions that return multiple variables may have variables that are important or not. There should be a way to flag any return value as nodiscard.

---@return number index
---@return {number:string} list
---@nodiscardall
---@return number nonimportantvariable
function getREALLYImportantList()

I suppose nodiscardall that marks any return above it to be important.
Maybe even @nodiscardabove would workout
