Assembly can refer to the size of this struct
as <code>reader__size</code> and the offsets of the two fields
as <code>reader_buf</code> and <code>reader_r</code>.
Hence, if register <code>R1</code> contains a pointer to
a <code>reader</code>, assembly can reference the <code>r</code> field
as <code>reader_r(R1)</code>.

<p>
The quantification "the set of all non-interface types" refers not just to all (non-interface)
types declared in the program at hand, but all possible types in all possible programs, and
hence is infinite.
Similarly, given the set of all non-interface types that implement a particular method, the
intersection of the method sets of those types will contain exactly that method, even if all
