It's in the 6.8.1 release notes (well, the -fdisambiguate-record-fields

Nice feature but feel like a band-aid. In particular it makes SYB style
programming more difficult because field labels aren't types.
Almost every other record syntax plan involves field labels as types so
you can do interesting type dispatch.
With this syntax, there is increasing probabilit

If so, then forcing the user manually to enumerate them at the top of a

Hi dear fellow ghc users,
I simply wanted to let people know that I apparently succeeded in
compiling a patched version of HDirect with GHC 6.8.1 (with typelibs
support).
At least, I could compile some of the examples and had very simple test

Dear GHC developers,
when compiling the function f x = if x them False else True
ghc-8.8.1 reports: " parse error on input `else' ".
When there is a large expession after `them', it is sometimes
difficult to locate a typo.
Why does not it report " parsing if-then-else: cannot find `then'
What about literate files? the inclusion of extended haskell files expand to
too much file extension in my opinion.

Hi Wolfgang,
you are right, this behaviour is a bit surprising. What you want to
observe can be obtained with, for example:
loop c = putChar c >> loop c
where loop is not a CAF anymore since it takes an argument.
In the definition that you gave, main is a CAF and gets evaluated only
