Hello!
I'm puzzled, if in Haskell it's possible to create a (pure) data structure,
consisting of 2 substructures referencing each other:
-------------------------
data AA = AA {
someData1 :: SomeData1
bb :: BB
}
data BB = BB {
someData2 :: SomeData2
aa :: AA
}
f :: SomeData1 -> SomeData2 -> AA
f somedata1 somedata2 = ??????????
-- Always True:
ghci> f == aa $ bb f
True
-------------------------
Any ideas?
