 1. run CollectArgsFailing.hs
 2. run CollectArgsPassing.hs

 My expectation is for both programs to be equivalent. However, the first
 program fails with `*** Exception: expectJust cpeBody:collect_args`. The
 second works as expected.

 {{{
 corey-mbp:tmp corey$ runhaskell CollectArgsIssueFailing.hs
 *** Exception: expectJust cpeBody:collect_args
 corey-mbp:tmp corey$ runhaskell CollectArgsIssuePassing.hs
 True
 }}}
