Improve error message when failing to parse a block We want to catch this error: ``` if (foo) bar; ``` as it's valid syntax in other languages, and say how to fix it. Unfortunately it didn't care if the suggestion made sense and just highlighted the unexpected token. Now it attempts to parse a statement, and if it succeeds, it shows the help message.
