Hi Matthijs,
This is a shameless plug for EMGM, a library for generic programming that
we've been working on at Utrecht.

Core types (in particular CoreExpr) are not instances of Show. They are
instances of Outputable, which allows them to be pretty printed.
However, this pretty printing is good to view the structure of the
expression that the CoreExpr represents, but doesn't show the structure
of the CoreExpr itself
You may find it useful to use External Core (supported in GHC 6.10),
which allows GHC to dump its Core representation into a text file with
a well-defined format:

There is a (relatively) stand-alone library for handling Core

Hi Brian,

SPJ might be able to give you some better answers, but this should help
get you started.

Hi all,
for my Master's thesis, I'm looking into functional hardware
descriptions, and in particular to translate haskell code into VHDL that
can be programmed into an FPGA.
For this, I'm using the GHC AP

If I hunt around a bit, I can maybe find my notes on translating to
Forth - my goal was to be able to run Haskell on all the printers at
work.

Dear GH Users,
I have been using the -fext-core option to generate *.hcr Files. I've also
read the document "An External Representationfor the Core Language."
There are still some things that confuse me.
Firstly, it seems, that Tuples are sometimes represented for example for
(a,b) as DataziTup
