Packages which contain all the resources any of their subpackages will need are called "enclosures".

§1. The idea of "enclosure" lets us create something "nearby". We are generally creating bytecode at a particular position in the hierarchy — say, in the current function being compiled. We then want to create some associated local resource, which can't be at that exact position, but which we want to keep nearby. (For example, a constant list mentioned in the function will need an associated array.)

The following creates a package in the enclosure surrounding the current emission position:

Looping Over Scope - §2(int hap, int hl) {
    package_request *PR = HierarchyLocations::attach_new_package(
        Emit::tree(), NULL, Emit::current_enclosure(), hap);
    return Hierarchy::make_iname_in(hl, PR);
}

§2. As noted above, literal values for constants which cannot be stored in a single word are a case in point. In general, these are represented in memory like so:

                        small block:
      ----------------> data
                        data
                        ...

The size of the small block varies from kind to kind,¹ but for any given kind this size is fixed. For example, a text has a small block of 2 words.

Often, but not always, the small block points to a larger and flexibly-sized block of data elsewhere:

                        small block:              large block:
      ----------------> metadata
                        ...
                        pointer ----------------> block value header
                        ...                       data
                                                  ...

The size of the large block, and the format of the small block and the "actual data", vary from kind to kind.

• ¹ Properly speaking, from constructor to constructor. All lists have the same size of small block. ↩
