  Go 1.22 includes a preview of a language change we are considering
  for a future version of Go: <a href="https://go.dev/wiki/RangefuncExperiment">range-over-function iterators</a>.
  Building with <code>GOEXPERIMENT=rangefunc</code> enables this feature.

Assume we have compiled a package containing the package clause
<code>package math</code>, which exports function <code>Sin</code>, and
installed the compiled package in the file identified by
<code>"lib/math"</code>.

We should be able to simplify the rules for comparable or delegate some of them
elsewhere since we have a section that clearly defines how interfaces implement
other interfaces based on their type sets. But this should get us going for now.

In general, machine-specific operations tend to appear as themselves, while more general concepts like
memory move and subroutine call and return are more abstract.
The details vary with architecture, and we apologize for the imprecision; the situation is not well-defined.

The assembler program is a way to parse a description of that
semi-abstract instruction set and turn it into instructions to be
