<script id="s1" src="foo.js"></script>
<script>
alert('foo.js contains' + _source_code_of('s1'))
</script>
Can _source_code_of
be implemented?

No, this would allow to retrieve the contents of any URL, which would break some security policies. (This would be an equivalent of an ajax get request without same-domain checks.)
However, since foo.js
is on the same domain than the page you can fetch it with an ajax request. Example with jQuery:
$.get('foo.js', function(source_code) {
alert('foo.js contains ' + source_code);
});
