Not familiar with C# runtime but I think that should be
@lexer::members not @lexer::override. Couldn't see any reference to
override action scope in the C# target. But if it's spitting out the
code in the generated file then that should work too. It looks like
the C# target funnels all errors through Lexer.ReportError so
something like this should work.
