    How to stop Core.asyncCall?

    Hi guys!

    Core.asyncCall is very handy for working with delays, personally I use it this way very frequently.
    But sometimes we need to close scene/popup before Core.asyncCall stopped executing.
    How to properly do it?
    	local function scaleTextsAndBtn()
		local tempFontScale=1.02
 
		Core.yield(.2)
		txt1_noads:setScale(tempFontScale)
		Core.yield(.1)
		txt1_noads:setScale(1)
 
		txt2_plusincome:setScale(tempFontScale)
		Core.yield(.1)
		txt2_plusincome:setScale(1)
 
		txt3_instantgift:setScale(tempFontScale)
		Core.yield(.1)
		txt3_instantgift:setScale(1) 
 
		txt4_dailyreward:setScale(tempFontScale) --scene may need to be closed somewhere here, and if it's closed, function naturally crashes
		Core.yield(.1)
		txt4_dailyreward:setScale(1)
 
 
		Core.yield(.1)
		btn_OK:setScale(1.04)
		Core.yield(.2)
		btn_OK:setScale(1)
	end
 
	Core.asyncCall(scaleTextsAndBtn)
    I guess it could be handy to have a command like 'Core.stopAsyncCall? (Or maybe not?)

      In fact, no. It seemed dangerous to attempt to stop a lua coroutine in the middle of its work. I felt that it was better if the developer could handle interruption by himself in his code. Ex:
      local interrupted=false
Core.asyncCall(function ()
 --Do stuff
 Core.yield(1) if interrupted then return end
 --More stuff
 Core.yield(1) if interrupted then return end
 -- Final stuff
end)
 
--Later
interrupted=true --Make sure the async call will stop ASAP
