The psome function detects the position into the source files where the function itself is called. It prints the object according a counter variable. Therefore, whenever the psome function is called inside a loop the object will be printed only a limited number of times. This can useful for debugging code in particular when the data structure we want to scan is quite big and we want to print only the first elements of it.

It's p(aw)some! Isn't it? :)
