Function Overloading I think?

I am working on cleaning up some code I wrote.  while debugging the code I was putting in lots of highlights to make sure I was searching the right regions and found the right image.  Since that seemed to add a lot of extra lines of code, I am working on creating some functions that will work better.  I have come up with this so far:


function eClick(reg, img, debug, sec)

local r, m

if debug then reg:highlight(sec) end

if reg:existsClick(img) then

r = true

if debug then

m = reg:getLastMatch()

m:highlight(sec)

end

else

r = false

end

return r

end

-- example
if eClick(Region(40, 50, 80, 80), 'target1.png', true, .25) then

eClick(Region(100, 75, 80, 80), 'target2.png', true, .25)

end




Is if possible to modify this to follow the current reg:function format?  so a call would look like


if Region(40, 50, 80, 80):eClick('target1.png', true, .25) then

Region(100, 75, 80, 80):eClick('target2.png', true, .25)

end
