G'day all.
Quoting Conal Elliott <[EMAIL PROTECTED]>:
That eta-expansion desugaring would lose sharing. Offhand, I don't know of
a desugaring that would do the trick and preserve sharing. Any ideas?
How about this?
f = let body = sort . nub
in \xs -> case xs of
[] -> [1]
(_:_) -> body
I suspect we're well out of the territory of mere "desugaring" here,
though.
Cheers,
Andrew Bromage
