Just to clarify:

OpenBSD's sh(1) and ksh(1) make it impossible to run code like

set -e
if eval "$string"; then
    echo ok
else
    echo not ok
fi

where "$string" is a piece of code that returns a non-zero exit status.
This script would not output anything with string=false, for example,
even though the eval occurs as a test within a conditional statement.
