\$\begingroup\$ @EricDuminil nice! I thought all the single character operators were quoted in the error message, but you're right: & isn't. Neat! Also, good find with the hex escape. I was struggling to find a shorter and non-stack-trace fatal error message other than a syntax error. \$\endgroup\$
