This looks good, and should help save work by not generating this data during a compilation.  But I'm wondering if we should go further and reduce the static code footprint of all these similar functions.  We could make these functions completely data-driven using compact signature strings.  For example, new_array_Type() when passes NOTNULL and INT and returns NOTNULL could be represented by something like "NIN".
