Changes in the Core language file syntax since GHC5.02?

[Dimitry Golubovsky]

Hi,

I asked this in the fa.haskell newsgroup, but since this is more 
GHC-specific, maybe this list is a better place to ask.

I am trying to learn the syntax of Core language files using the paper 
by Andrew Tolmach named "An External Representation for the GHC Core 
Language". This was a draft for the version 5.02. Have there been any 
improvements to the Core language definitions since that version and 
during the v6.0 implementation? Are they summarized in a document? Or 
maybe a fresher version of the paper is available?

Thanks,
