this as lvalue?

[Andrej Mitrovic]

++ on that bug report.

On a similar note, today I was rewriting a dsource class example
because I wanted to show that you can use "this.name" to assign to
fields that have the same name as a parameter. And then I accidentally
made this mistake when writing a different method:

class Foo
{
    string name;

    void printMe()
    {
        name = "test";
        writefln("printMe.name = %s, Foo.name = %s", name, this.name);
    }
}

The "name" in the printMe method was supossed to be the declaration
'string name = "test";'. But I forgot to put the type before name, and
inadvertently modified the class variable name. In this case I wasn't
even passing any parameters, so this is unfortunately impossible to
flag as an error because using "this" is optional in D.
