As for the hard limit, pretty much.

I would consider anything more than four indents a code smell. That is,
four is unexceptional; five would make me look over the code to see if it
could be refactored; six would make me look at it *carefully*; eight
would have me questioning my own sanity. I wouldn't give a hard limit
beyond which I would "never" go beyond, but I find it difficult to
imagine what drugs I'd need to be on to go beyond eight.
