What is the best way to receive information from a ModuleScript more than once?

Straightforward question.

ModuleScripts can only return values once to each client and once to the server.

What I have done in the past is send a location to the Module that it can put a StringValue or IntValue into. Then, I would tell the script to wait until a StringValue or IntValue appears:

repeat wait() until script:FindFirstChild("ValueWeAreWaitingFor") ~= nil;

Is there a better way? I notice Quenty's NevermoreEngine has a LoadCustomLibrary function in it. He says that Nevermore Engine caches ModuleScripts. All it seems to do is return a require() of the modules? (I may have just answered my question)

I am 50% sure this is what becomes the LoadCustomLibrary function in other scripts that use it:

local function LoadLibrary(LibraryName)
        --- Load's a modular script and packages it as a library. 
        -- @param LibraryName A string of the resource that ist the LibraryName

        -- print(Configuration.PrintHeader .. "Loading Library " .. LibraryName)

        local ModularScript = GetResource(LibraryName)

        if ModularScript then
            if ModularScript:IsA("ModuleScript") then
                -- print(Configuration.PrintHeader .. "Loading Library " .. ModularScript:GetFullName())
                local LibraryDefinition = require(ModularScript)

                --[[if type(LibraryDefinition) == "table" then
                    -- Import native definitions
                    for Name, Value in pairs(NativeImports) do
                        if LibraryDefinition[Name] == nil then
                            LibraryDefinition[Name] = Value
                        end
                    end
                --else
                    --error(Configuration.PrintHeader .. " Library '" .. LibraryName .. "' did not return a table, returned a '" .. type(LibraryDefinition) .. "' value, '" .. tostring(LibraryDefinition) .. "'")
                end--]]

                return LibraryDefinition
            else
                error(Configuration.PrintHeader .. " The resource " .. LibraryName 
                    .. " is not a ModularScript, as expected, it is a " 
                    .. ModularScript.ClassName, 2
                )
            end
        else
            error(Configuration.PrintHeader .. " Could not identify a library known as '" .. LibraryName .. "'", 2)
        end
    end

EDIT Specifically what I am looking for a more efficient way to do is: I am making a fun Cribbage game on Roblox, and I wrote a module to find the number of points in the hand. Here is the module, if you really want to see my code. Anyways, I have a localscript that is going to access the module like so:

local CribLib = require(game:GetService("ReplicatedStorage").CribLib)
--               ...  ...  ...  ..
local answers = script:WaitForChild("CardInstructions")
local keepCards = answers:WaitForChild("keepCards")
local tossCards = answers:WaitForChild("tossCards")
local keepCards = game.HttpService:JSONDecode(keepCards.Value)
local tossCards = game.HttpService:JSONDecode(tossCards.Value)
answers:Destroy()

I specifically, was wondering if there is a better method for receiving information from the Module.
