"=begin" should start at the beginning of a line. You cannot indent
them.

Any good reason for this?

I suppose it must be slower for Ruby to strip leading whitespace, but
only very slightly.

Why would I want to indent block comments? So they're at the same
indentation as the code I'm commenting. Keeps things neat and tidy. :-)

It might be because of this conflict:

x =begin
3/0
rescue
"div by 0"
end
