More values typeof([]) can be implicitly converted to - weaker 
typing, that simple. Actually I'd love to be able to specify 
precisely typed empty array literal, like [uint] or [uint:bool] 
but can't find a good syntax to propose. Currently array literals 
are very special and is does harm the type system.
