} Problem is that set -e or ERREXIT kill my shell when called in a sourced 
} script.

This should work:

    trap 'return $?' ZERR

Or if you want to get fancier:

    [[ -o interactive ]] && trap 'return $?' ZERR || set -e

To remove the trap automatically (very recent zsh versions only):

    trap '(){ trap - ZERR; return $1 } $?' ZERR
