The program:
x = v where v = 2 where
main = putStrLn "hello world"
parses as:
x = v where v = 2 main = putStrLn "hello world"
which is incorrect.
(in general, the parser can't deal with empty where clauses) as in:
x = 'a' where class A a where
this gives a parse error because it's waiting for a real declaration inside of the first where clause.
Thanks for the report. All these are due to the implementation of layout omitting the rule about inserting empty braces (now fixed in CVS).
it also can't deal with empty statements:
v = do {return 'a';;}
should be accepted but results in a parser error.
This isn't Haskell.
