// corresponds to is to look at YAML "tags" (e.g. `!Foo`). Then, different
// tags (`!ELF`, `!COFF`, etc.) would be used to discriminate between them.
// Interpreting the tags is needed eventually for when writing test cases,
// so that we can e.g. have `!Archive` contain a sequence of `!ELF`, and
// just Do The Right Thing. However, interpreting these tags and acting on
// them appropriately requires some work in the YAML parser and the YAMLIO
// library.
