After some binary search work (I need to automatize this...) I found that this 

Caused Nemerle to fail quite fast during bootstrap:

make[3]: Entering directory `/home/users/nemweb/nemerle/ncc'
COMPILE [stage1] Nemerle.dll

Func1 f)

I looked at the code of add_derived_members and there are not explicit casts 
out there. This is probably happening on some of casts performed by compiler, 
which are known to be *valid*. 

Just tell me if I should do some more debugging or file a bug report.
