I found that in most cases, the parts of code that I want to b-comment always start with a comment (i.e a complete sub with comment s before the sub). But now I understand the new system, so I should block comment from the line after the comment.
I also preferred the old method, but maybe because I didn't know how the new one works.
I guess the way we should comment lines now would be at the end of each line.
for i = 1 to 10 'looping.
log(i) 'logging.
next
