[Ferm] hook restriction

[Kiss Gabor (Bitman)]

Dear Max,

Why this restriction is required in subroutine enter()?

            if ($keyword eq '@hook') {
                error('"hook" must be the first token in a command')
                  if exists $rule{domain};

I could create quite elagant functions if domain were known
at the point of hook definition. (I.e. I need hooks inside domain{...} )

Regards

Gabor
