Research direction
Start by opening the linked CodeWorld Haskell program and reproducing the reported GHC error about the missing main action. Trace where compiler diagnostics are surfaced for that program; done should mean the missing-main case presents a more helpful message, though the issue does not specify the desired wording or affected files.
Written by the indexing model from the issue text.
