This fixes a problem with lens-aeson support (eta-hackage #120)
Description
Ensure the trampoline function permits DataCons as well as Thunks. This seems to permit lens libraries such as lens-aeson to function properly.
How Has This Been Tested?
./runtests.sh is passing all tests except arr003, which was failing before this change. I also reproduced the issue in eta-hackage (#120) and verified that this change resolved it.
