Re^2: Is an empty block not a block?

[chas]

But if so, why is a semicolon necessary. It isn't if the hashref isn't empty as in:

{blah, "blah"}
print "This is fine\n";

I don't see why being empty changes anything essential.
Perhaps in the empty case, perl doesn't know what it is, and that's the problem...
(I guess {blah, "blah"} is considered to be a hashref; I don't know what else it would be...)
