    {- Note [Interface file stages]
       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Interface files have two possible stages.

    * A partial stage built from the result of the core pipeline.
    * A fully instantiated form. Which also includes fingerprints and
      potentially information provided by backends.

    We can build a full interface file two ways:
    * Directly from a partial one:
      Then we omit backend information and mostly compute fingerprints.
    * From a partial one + information produced by a backend.
      Then we store the provided information and fingerprint both.

    Note [Strictness in ModIface]
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    The ModIface is the Haskell representation of an interface (.hi) file.

    * During compilation we write out ModIface values to disk for files
      that we have just compiled
    * For packages that we depend on we load the ModIface from disk.

    Some fields in the ModIface are deliberately lazy because when we read
    an interface file we don't always need all the parts. For example, an
    interface file contains information about documentation which is often
    not needed during compilation. This is achieved using the lazyPut/lazyGet pair.
    If the field was strict then we would pointlessly load this information into memory.

    On the other hand, if we create a ModIface but **don't** write it to
    disk then to avoid space leaks we need to make sure to deepseq all these lazy fields
    because the ModIface might live for a long time (for instance in a GHCi session).
    That's why in GHC.Driver.Main.hscMaybeWriteIface there is the call to
    forceModIface.
