I feel like I have way too much code of the form:
changeGpart (C a b c d e f g h i) g' =
C a b c d e f g' h i
So, I got excited reading Simon and Mark's
"Lightweight Extensible Records For Haskell" paper
as a way to get rid of this cruft. I immediately
started GHCi, typed {a="Hello world"}, and got an
error.
Is the feature described in the paper just a
proposal or is there a switch somethere to enable
it?
Alternatively, perhaps this code is a common
beginner mistake due to ignorance of the proper
idiom...
