[Question] EventManager - about event return value

[vvedge]

I'm quite new to lua and TTS scripting and first would like to thank you for your work which is a great source of inspiration :)
Looking at your code raised some questions, I hope it is OK to ask here

What I understand from AddHandler code :
it sets a global function named after the event
it took into consideration that such global function could already exists
new global function will call potential existing one + each registered handler
My question is about the return value : it looks like it returns the last handler return value... is it intended behaviour and why the last ?
I would have expected to be the "and" of all the returned values

_G[event] = function(...)
    local globalHandler = EventManager.globalHandlers[event]
    local returnValue
    if globalHandler then
        returnValue = globalHandler(...)
    end

    for _, handler in ipairs(EventManager.handlers[event]) do
        returnValue = handler(...) and returnValue
    end
    return returnValue
end

So, if I add many tryObjectEnterContainer handlers, the return value will be true if all handlers succeded and false if at least one failed

Also, why FireEvent doesn't return any value ?
wouldn't it be ok to just call _G[event](...) ?
