Ah, I was using the next-4.2 branch and missed this fix in master, sorry 
for the noise.

However, the parser problem is solved, but named mark maps are still
not working:

anonymous maps work as expected:

   # nft add rule ip mangle OUTPUT mark set ip saddr map {  192.168.0.10 
: 0x1 }

named maps do not:

   # nft add map mangle CLASS05 "{ type ipv4_addr : mark; }"
   # nft add element mangle CLASS05 { 192.168.0.10 : 0x1 }
   # nft add rule ip mangle OUTPUT mark set ip saddr map @CLASS05
   <cmdline>:1:1-56: Error: Could not process rule: Invalid argument

Any idea?
