Good question. Why not. I use hashes all the time, amd never have to do
anything more than $hashref->{$key} for any given level of dereferencing. If I
am actually addressing a hash name directly [very rare] I use $hashname{$key}.
Have you had problems using the direct form. What you are doing defeats the
entire purpose of a hash.

Use the arrow operator. See syntax above. Or you could:
$$hashname{$key}
But I have come to see that as relatively ugly. If you get tused to the arrow
operator, it will start to speak to you.
