In reply to @im_rob "I have a question": i believe you are approaching it from
wrong point

nim objects are not like python objects that has init or likes
in fact, newXxxx is just a convention, it's just a name style we agreed to use
when making library, but theres no "constructor" or anything like that

think of it as you giving one convenience procedure to initialize object while
developer still can do anything they want, just you giving "default setting"
that developer can opt to not use
