This code works:
my $href = shift @_; # get reference to hash
my %h = %{$href}; # dereference hash
This one does not:
my %h = %{shift @_};
As well as this one:
my %h = ${$_[0]}
Why?

Hi, I would like to construct a hash table that looks up keys in sequences (strings) of bytes ranging from 1 to 15 bytes.
