The Haskell'98 Report already uses an informal notion of a "core"
language, into which other syntactic constructs are translated.
I think in Haskell-prime we ought to define this core precisely
One can even imagine someone developing a pure H-core compiler, with
the fuller language implemented as a pre-processor over the top!
(I know at least one person who would prefer to write programs in
core rather than Haskell'98...)
