Hi,

I am currently looking at:

	Int32.pack
	Int32.unpack

functions.

If I try:

	open Batteries_uni

	let s = String.create 4
	Int32.pack s 0 42_l;

everything seems fine.

However, if I try:

	let s = String.create 5
	Int32.pack s 0 42_l;

I am getting an exception:

	Fatal error: exception Failure("Int32.pack: pos + 4 not within string")

I would like to ask: is this the expected behavior?
Why doesn't /pack/ simply use the first 4 bytes to the string and ignore all the other bytes that may be part of the string?
