Ok, this couldn't get much simpler - all I want to do is read multiple lines (or records) from a file.

I could do this :-

my @slurp = <IN>;
while (my @chunk = splice(@slurp, 0, 10)) {
  # do stuff
}

Or I could go completely mad and do this :-

while (my @chunk = map{scalar<IN>||()} 1..10) {
  # do stuff
}

[download]

I don't want to read the whole file into memory, so the first solution is no good for me, but the second solution seems a little silly.

Anybody got any better ideas?

Have fun,

rdw
