Access "AddOn namespace" (addonName, addonTable = ...) from outside?

[fuba]

Hi there,

i got a question about AddOn namespace or more specific the "addonTable".

What exactly i mean?
Some AddOns did not set there AddOn Table for Global Access (becasue?! Reasons!)

Like this:

local addonName, addonTable = ...

or this:

local _, Engine = ...

I know i can edit this AddOn(s) manually by adding a Global Variable like:

local addonName, addonTable = ...
_G[addonName] = addonTable

or

local _, Engine = ...
_G.MyAddOnEngine = Engine

BUT there must be another way, without "touching" the original addon, right?

I found some Threads here that say "just set "Dependencies" in your TOC file for the AddOn and you can access it.
But i cant get it work!

Is there anything i look over? ^^

Maybe someone can help!

greetings,
fuba
