There's nothing to work around. 'set -e' is behaving as required by
POSIX, which just happens to be a different behavior than what you want.
There is no option in bash to get the behavior you want, unfortunately.

It doesn't disable 'set -e' inside ALL function bodies, but only inside
function bodies where the function call appears inside a context where
'set -e' is ignored (such as in the condition of 'if'). It's
non-intuitive, and therefore my advice is to never rely on 'set -e'.
