   My apologies, after fiddling around with the extension's code for a while, I realised all I had to do was define VM = {} manually, like this:

   VM = {}
   
   local hookParamTypes = {
   	PlayerUpdate = { "Player", "float" },
   }
   
   function VM.OnCompileFunctionParam(next, hookCallback, hookParam)
   	if next(hookCallback, hookParam) then return true end
   
   	local addHookArgs = hookCallback.parent
   	if addHookArgs.type ~= "callargs" then return end
   
   	local addHookCall = addHookArgs.parent
   	local addHookName = addHookCall.node[1]
   	if addHookName ~= "addHook" then return end
   
   	if addHookArgs[1].type ~= "string" then return end
   
   	local hookType = addHookArgs[1][1]
   	if hookType ~= "PlayerUpdate" then return end
   
   	local hookParams = hookParam.parent
   	local hookParamName = hookParam[1]
   
   	local hookParamIndex = nil
   	for i = 1, #hookParams do
   		local otherParamName = hookParams[i][1]
   		if otherParamName == hookParamName then
   			hookParamIndex = i
   			break
   		end
   	end
   
   	if not hookParamIndex then return end
   
   	-- local type = vm.declareGlobal("type", "TestClass", uri)
   	-- vm.setNode(source, vm.createNode(type, source))
   end

   It works now, but that wiki page should probably be updated, since the example it gives for this function is very unclear and not functional at all.

   maybe overload function:
