Just a hunch, but what happens if you add a semicolon at the end of
the first "var" line?

The only change I made to it was to add types to the arguments to functions and have it generate C# code. It didn't work :-( The following function declaration works just fine:

So if you need to test you could take the above function declaration (take out the argument type after the colon if you haven't modified the grammar to handle types) and you should get the same error (starting at functionDeclaration). Any ideas?
