This doesn't work:
class Foo {
this() {
this = new Foo;
}
}
Error: Cannot modify 'this'
However you can do this:
class Foo {
this() {
auto p = &this;
*p = new Foo();
}
}
It even changes the value of this!
Should that compile? I mean, it's the same as modifying 'this'...

Looking at the DMD Source Guide it says "The lexer transforms the file

Why is this step taken instead of, say, just calling a function that
