Others have already commented on many aspects of this discussion, but
I just wanted to mention that cabal has an '--allow-newer' flag to
disregard these constraints, so '--allow-newer=base' would allow you
to try and compile this package with GHC 8. Since GHC 8 is very recent
though and base 4.3 is very old, I imagine it won't work. In general I
think many packages haven't been updated for GHC 8 yet.

Why would a package developer want to upper bound the version number for packages like base? For example, the clash package requires
base >= 4.2 && base <= 4.3
Consequently, it refuses to install with the latest ghc provided with the Haskell Platform (8.0.1).
Does this mean that assuming that future versions of the platform will remain backwards compatible with prior versions is unsafe?
