I don't know if it still works, but it did in Linux little over 10 years 
back. Proxy-arp:ed all the IPs in the /27 in the /24 and everything was 
fine (legacy reasons plus radiolink which I didn't want to run a lot of 
broadcasts over). There are "legitimate" cases where you might want to do 
this.
