Jason was close.  Try this instead:

 $_[0]->set($state);

This is a common problem that people have in perl.  You use the @xyz when
you want to point to all or a slice of the list array, and use $xyz[#] when
you want to point to a specific entry.  @_[0] is a 'slice' with only one
entry.   @_[0,1] would have to entries etc.   So you want $_[0] to point to
the first entry.

I don't know why 'set $xyz[0] $state' does not work.  Seems like a perl bug.
