That _is_ cool.

The reason that the o,e are passed is that the def is of an unnamed function that is the eventhandler method. In C#, if you type in the line you did, the IDE (in VS2010) will complain that the function you named is not available. You then have to define that method.

private void ButtonClick(object o, EventArgs e)
{

}

in order to compile, of course. So that still looks like a lot of extra typing to me. <s> In fact, it looks as though it is twice as much typing, if not more. If I can cut out half the typing I do (and I don't think it will be that much, probably more like 20-30%) over the next 15 years of my working career, I would like that. This is all individual, of course; I have a couple of friends who type code out at 90+ words per minute. For myself (I'm sure this is not universal), having fewer superfluous words means I can focus on the meat of what is being done. à chacun son goût, as they say.

>>At the most, Boo's compiler does more, as I indicated. For example, if I have a button b, then I can define an eventhandler and an eventhandler method like so:

>>b.Click += def(o,e):
>> b.Text = "Clicked"
