	A lot.

	I will cry for any wasted memory byte or CPU tick (as some of my skills
come from ancient days when any bit or tick has value), but well, when
style(9) discourages initializers, we must avoid the v=v construct ...

	;-)

	BTW, I understand that the comments are suggestions how to do thinks
better. I hoped for those when decided to spend time to PR creation. I
can learn from it.

	Thanks
