Странно. Тогда не знаю (c). Я думал будет что-то вроде:

Scalar value @hash{123} better written as $hash{123} at /home/kinjo/at.pl  
line 6 (#1)
     (W syntax) You've used a hash slice (indicated by @) to select a single
     element of a hash.  Generally it's better to ask for a scalar value
     (indicated by $).  The difference is that $foo{&bar} always behaves
     like a scalar, both when assigning to it and when evaluating its
     argument, while @foo{&bar} behaves like a list when you assign to it,
     and provides a list context to its subscript, which can do weird things
     if you're expecting only one subscript.

     On the other hand, if you were actually hoping to treat the hash  
element
     as a list, you need to look into how references work, because Perl will
     not magically convert between scalars and lists for you.  See
     perlref.

Удачи.
