Hi Stefan,
You might like to read my paper "Initializing Mutually Referential Abstract Objects", http://dx.doi.org/10.1016/j.entcs.2005.11.038, where I argue that this is a serious limitation, and argue the case for an alternative. Interestingly Scala is considering using the kind of recursive initialization I propose in the paper, though much more extensively than I originally proposed.
Cheers & best wishes,
Don

This is the case in SML: you need to go through a `ref' cell in order to
create a cycle. This has very rarely been presented as
a serious limitation. OCaml's trick is occasionally useful, but I don't
think anybody would lose her sleep over it.
