On thing to add here:
The 'n's in this code are all different bindings. So there's no way
to get a closure which captures the values of all 'n's.
Thus in other code (but not in this case) you could have written:
let pr_args () =
pr " char *%s = args.%s\n" n n
in
where the value of 'n' would be captured in the closure 'pr_args', and
not have to be given explicitly each time.
