The problem is that those declarations aren't really doing what you think they are; we are simply engaging in 'type theater'. 

The annotations indicate what the author thought the resulting type of the RHS expression would be, or perhaps were at one time. But they are only showing what we are asking the compiler to coerce the result into. I would argue that the number of times we really want to coerce the result of an expression to something new are relatively rare, and could be handled be the new 'type' syntax, or explicit cast declarations.
