  "When this option is on, if a simple command fails for any of the reasons
  listed in Consequences of Shell Errors or returns an exit status value >0,
  and is not part of the compound list following a while, until, or if keyword,
  and is not a part of an AND or OR list, and is not a pipeline preceded by the

In your original example, which I believe looked something like:

  if ! myfunc; then

set -e is not in effect for two reasons: the if, and the !.  Either one
would be sufficient to disable it.  You've got both.

The workaround is "stop trying to use set -e".
