I would like the hypothetical errfail option to:
* Behave like errexit at the top level (outside of functions).
* Be inherited by functions, subshells, and command substitution.
* Inside functions,
I would still propose that a simple and powerful way to extend Bash with
exception handling would be to extend the ERR trap by passing it some metadata
about the type and location of the exception incurred so that it can be handled
by user code. This proposal allows us to largely avoid having to an

Hi all,
the errexit option can be very useful in simple scripts. This option
is being ignored in many contexts like lists and conditionals though.
I understand that this is "by design" and that errexit cannot be
"fixed" to behave more reasonably. Still, this makes bash a lot less
useful than it co
