This is nasty. The following
```
if entry.answers.contains answer then pure () -- if answer was already found, then do nothing
else
let newEntry := { answers := entry.answers.push answer, .. entry };
modify $ fun s => { tableEntries := s.tableEntries.insert key newEntry, .. s };
entry.waiters.forM (wakeUp answer)
```
was being parsed as
```
if entry.answers.contains answer then pure () -- if answer was already found, then do nothing
else
(let newEntry := { answers := entry.answers.push answer, .. entry };
modify $ fun s => { tableEntries := s.tableEntries.insert key newEntry, .. s });
entry.waiters.forM (wakeUp answer)
```
