[zoffixznet]

Issue Description

Example Code

{
    {
        is_run q[Supply.interval(1).tap(-> { say 'hi' }); sleep 3;], {
            status => 0,
            err => /
                'Unhandled exception in code scheduled on thread' .+
                'Too many positionals' .+ 'expected 0 arguments but got 1'
            /
        }, '.tap block with incorrect signature must fail';
    }
}
