[Haskell-cafe] Cyclic Inclusions

[ajb at spamcop.net]

G'day.

Quoting "C.M.Brown" <cmb21 at kent.ac.uk>:

GHC generates .hi files for most modules automatically.  The only reason
why hi-boot files are needed for cyclic imports is because of the
possibility that you can't generate a .hi file from the module alone.  If
you could do that, then you could support cyclic imports without needing
hi-boot files.
