Why doesn't it exit the shell?
$ set -e
$ echo $(false)
Shouldn't the error code of $(false) command substitution be checked by set
-e before passing stdout to the echo builtin?
Isn't it the most logical behavior that most people would expect of set -e?

(if it matters)
Thanks
Seriously, can we just put a trap on all messages to this list that have the
string 'set -e' in it? Just point the sender to a message that tells them to
not use it. We could even tell them that the functionality is a huge misteak
that was perpetrated upon the whole of mankind and that we're all just really
really sorry that it ever happened. In fact the author of this message is
probably dead from having generated an error by explaining it while his dash e
was set.
So, in conclusion, I would like to say on behalf of the FS community and
mankind in general that you should not use -e any more. If it would help, I'd
be willing to spend about $10 for maximum postage to send this announcement to
The Proper Address so that everyone would know about this For Ever More.
I'm sorry. I'm sorry that I'm sorry. And, I'm sorry that I'm sorrowful about
feeling sorry.
