Not really, or at least, not if I understand what you mean. This
code, for instance:
var Thingy = Class.create({
initialize: function(name)
{
this.name = name;
},
showName: function()
{
alert("this.name = " + this.name);
},
doSomething: function()
{
(function(){
alert("this.name = " + this.name);
})();
}
});
If I call it like this:
var t;
t = new Thingy('Fred');
t.showName();
t.doSomething();
...first alerts "this.name = Fred" (from showName) and then "this.name
= " (from doSomething). The closure inside doSomething() does not
inherit "this" from the scope in which it's called, so "this" is
"window" within it. Like all other functions, "this" is determined by
*how* it's called, not where.
Granted closures do inherit other aspects of context (in-scope vars
and such), so if that's what you mean, I take your point. But I think
that's a bit apples and oranges.

Just my two pennies worth, but it worked the way *I* expected it to.
I haven't been using Prototype that long and I remember not being
surprised by this, because it worked the way functions in general
work: I didn't explicitly supply a context, and it got the global
object. So I found it "intuitive" and would be surprised if it were
something else without me telling it to be. Just FWIW.
