No more confusing to me than to have to enter my email address twice. 8-)
Personally, I just clip it out of one box and paste it in the other,
defeating the purpose.
If we can determine the bounds of the entire expression, and can determine
if it is an &and, then we probably should not perform tests 2 and 3. I am
not sure that state machine is sophisticated enough to do that, but it
is in the check_order routine of Vend::Order, or more precisely &chain_checks.
I can see right now the problem is that we have no real way to bound
the expression. So probably for right now, there is no solution short
of enhancing the error tag to allow display of only the first error.
