Screen class execution and screen template rendering are perfrormed before
Layout rendering, so the screen class had a chance to run data.setTitle() and
screen template could run $data.setTitle() too.
Embeding javascript is also possible to implement - all is between the programer
and web designer. For example: the screen class could drop a Hastable containing
keys 'functions', 'onCommit', 'onLoad' under the key 'script' into the context,
and the designer made a layout template this way
<html>
<head>
<script language="javascript">
$script.functions
function fun() {
// designers js
}
function sendForm() {
// designers js
$script.onCommit
}
</script>
</head>
<body onLoad="fun();$script.onLoad">
a page with a form ....
</body>
</html>

People will find a way to misuse your code no matter how hard you try.
The good part is that it's them who'll be maintaing the resulting mess. :)

I'd really like to learn more about this new framework, because rigtht now
integrating WebMacro with FreeMarker sounds to me like fitting a square peg into
a round hole...
