e.g. I don't want to see the day subtle bugs due to forgetting to go and 
mark this prototype as @system crop up:

Consider it. On systems with HAS_GETDELIM, stdin.byLine which was 
previously inferred @system now is inferred @safe. All because of stuff 
like this was missed. What a fun bug to track down and fix.
