Can you mention what you need type information for? If it is to detect
higher order functions (as you have mentioned in IRC conversations
with me) then in about a week I am going to announce a Yhc.Core first
order transformation, which will remove that issue for you. In general
the lack of types in Yhc.Core has not proved a major issue for anyone
- if there is anyone who does absolutely require type information in
their intermediate language and therefore cannot use Yhc.Core, I'd be
very interested to hear from them.

Igloo submitted a few patches in the last week to get GHC.Core working
again. It doesn't have the same infrastructure support as Yhc.Core,
but it does have the advantage of having the GHC team behind it.

I (obviously...) would like you to use Yhc.Core, if you could expand
on why that isn't appropriate for you then perhaps you'll either get
improvements into Yhc.Core or some hints from the GHC team :)
