Make Region.click() arguments optional

But this means some exception to the general API concept, which means with a Region.click(PSMRL) to restrict the find operation with PS to the given Region.
When using click(MRL) it is not necessary to specify a Region, since the argument denotes an absolute click point.

so the above example could be written:

for f in findAll(findobjs):
  area = Region(f.nearby(100))
  click(area)

So with your approach you have to write an additional dot ;-)
And this does not have any impact on performance.

But if it is accepted by the developers, I would like to generalize this request:

a click() (no arguments given) should click:

Match.click() --- the defined target clickpoint
Region.click() --- the center
click() --- center of SCREEN
Location.click() --- the given point

same goes for rightClick(), doubleClick().

I incline to support only one way to specify the target of an action, i.e. click(target).
A problem with click() is that it's unreadable and hard to understand what happens if someone just write click() without a region. and arguments.
(It doesn't make sense if click() does click at the center of SCREEN. It may make sense if it clicks at the current location of the cursor, but it would be inconsistent with region.click().)

I fully agree with Sean.
So lets set it "won't fix"

in X-1.0

click()

will click the last match of the region if any, otherwise it will click the center (or targetOffset if region is a Match)
