in thread A different OO approach

A single hash is a special case with \(). From perlref.

As a special case, "\(@foo)" returns a list of refer- ences to the contents of @foo, not a reference to @foo itself. Likewise for %foo, except that the key refer- ences are to copies (since the keys are just strings rather than full-fledged scalars).

Annoying eh?
