One thing I'd *really* like to have is proper escape analysis and
inlining of scope delegates. I've been waiting a long time for this, and
there are no signs of implementation in sight. :-(

I don't see what luck has to do with it...  Currently, I lack just time
and adequate understanding of DMD internals; if I had both, I'd rip out
the AA implementation from DMD right now, and replace it with something
saner.

	struct S {
		this() {}
	}
	
DMD output:

/tmp/test.d(2): Error: constructor test.S.this default constructor for structs only allowed with @disable and no body
