Oh yeah there's no way this has any affect on performance. A smart
compiler might even be able optimize the call away entirely. Even if it
couldn't, it's about as fast as an operation could possibly be.

Yeah I figure this is the reasoning. Personally I don't like having
noops for this sort of code structure reasoning, but I can see how rules
like "everything gets init'ed" is also a fair strategy. Half of my
question was simply whether that is the case or if possible it was just
a mistake when older versions that did something could be removed (e.g.
the code example you put int).

Thanks for the response!
