You should be able to use `std.algorithm.take` to read exactly 5 
integers. However, in order to read up to the first empty line, 
for example, the input would have to be a forward range (= 
"rewindable"), which stdin.byLine of course is not. Maybe you 
could constructor a wrapper range that caches input lines as 
necessary.
