size of an IO list
Mon Mar 7 11:20:18 CET 2005
As usual, the hardest part is usually coming up with a good name.
After some discussion, Kenneth and I come up with the following
suggestion for TWO new BIFs.
where iolist_to_binary/1 will work like this
but be much faster (and obviously not build the temporary binary).
The reason for the new iolist_to_binary/1 BIF is that is not clear
that iolist_size/1 is any way releated to list_to_binary/1.
Comments? Other name suggestions?
