Maybe, but it is really not. What you are asking for is a scalar.
Therefore having the scalar indicator at the start of the identifer
tells the interpreter to seek the reult in scalar context. In the
case of a hash reference, this means "The scalar pointed to by the
reference $x and hash key $i". The expression
%{$x} means "The hash pointed to by hash reference $x"
