Would {}{} be
1) a block followed by a hash constructor,
2) a hash constructor followed by a block,
3) a hash constructor followed by a hash constructor, or
4) a block followed by a block?

They are not equivalent. At least, they are not equivalent if found at the end of a sub. The syntax error forces the user to disambiguate.
