I found no evaluation for any families so I could do
	nft add chain arp x y { type filter hook input priority -300;}
without any problem, which would be translated to 'raw'.

So I shouldn't have the possibility to add this priority? In this case, I think
the evaluation of the numerical value should be refined, but putting the
text->number translation into the evaluation phase does not seem approppriate to
me.
