----------------
Ah, wait, yes this also prevents the crash if I remove the `CurLexer.reset()`
and use `CurLexer->cutOffLexing()`, but it not only produces an error about a
missing '}', but an error about an extra '}' just after, which doesn't really
make sense. That means it's inspecting tokens past the EOF that was injected.
