    this.somevar='this is Foo';
}
Foo.prototype={
    bar:{
        somevar:'this is bar'
        ,foo:function(){

I think perhaps the scoping rules of the language will not allow this in any straightforward way. The best suggestion I can come up with to get what you want (short of renaming somevar to get rid of the clash in the first place) is to use apply() to change the value of this inside of foo(), like:

var instance = new Foo();
instance.bar.foo.apply(instance);
