Research direction

Start with _hyperscript.js and trace how the direct log $obj.a expression is evaluated versus the install logval(val: $obj.a) behavior argument. Reproduce the issue with the provided HTML, then verify that clicking the second button logs 10 instead of undefined.

Description

<html>
        <script src="./_hyperscript.js"></script>

        <script type="text/hyperscript">
                init
                        set $obj to {a:10,b:40}
                end

                behavior logval(val)
                        on click
                                log val
                        end
                end
        </script>
        <body>
                <button _="on click log $obj.a"> <!-- >> 10 -->
                        first button
                </button>
                <button _="install logval(val: $obj.a)"> <!-- >> undefined -->
                        second button
                </button>
        </body>
</html>

It is expected for 10 to appear in the console as a result of pressing the second button but undefined is returned .
