Of course "pack" can be a noun.  I didn't say otherwise (presuming that your reference to nouns versus verbs was in reference to one of my posts on that point).  However, just as you've used it, a "pack" is a collection or holder of things.  Hence, it doesn't work in this context because the type in question holds a single integer type of some number of bits/octets.
