This makes sure that the deref happens last, and that's what you want.
This roots in the precedence of perl operators. % is kind of term operator, which takes the highest precedence. ->takes the second highest.

That would work. I would probably prefer to modify the
param method and have it return a list in list context
so that
my %CF = $self -> param ('CPref');
just works. But then, I don't know how 'param' is used
in list context already, so it might not be feasible.

Thanks to BrowserUk and pg for the fix and the concise reason why.
Abigal: param is from CGI::Application module. I'm planning to use as is and not override it.

Returning a hashref is a lot more efficient than a hash, because of all the flattening Perl does to the hash when passing one back from a subroutine. In a CGI program, a method like param() could be used a lot, so it's important to optimize it.

That's why I said I would change it to return a list in
*list context*. Returning a hashref may be more efficient,
but if you flatten it to a list right after returning it,
you've lost most of your gain.
