Change strategy for handling true and false to avoid some initialization order problems and improve performance. Add support for negative integer literals. Update samples to reflect true/false change.

{
	foo <- { 42 }
	#{
		qux <- foo:
		bar <- #{
			
			baz <- {
				foo:
			}
			
		}
		
		main <- {
			print: (string: (bar baz))
		}
	}
