example "Core syntax" is ancient

User's guide section 4.19.5 has some funky "Core syntax" that (according to git blame) dates back to at least 2000, and probably longer ago than that. It could use an update.

added Tbug Trac import documentation labels

Wow, that's very different, the same comments don't even apply. Is it necessary to re-comment the code?

I've attached a log of the output.

Attached file ddumpdslog (download).

If you understand that output, could you indeed add some comments. Then we can update the documentation and close this ticket. The current version is not very helpful.

    User's guide: delete ancient "Core syntax" example

There are resources online to learn how to read GHC Core, such as:

• http://stackoverflow.com/questions/6121146/reading-ghc-core
• http://blog.ezyang.com/2011/04/tracing-the-compilation-of-hello-factorial/

If someone feels like contributing a new section on Core to the User's guide, they are of course free to do so. The section I just deleted wasn't doing any good.
