Yes, the syntax is very limited (too conservative) for the using keyword. The \ causes the entire syntaxing to fail, as its not acceptable per the grammar. I haven't made any improvement in this area either, with my PR #155 or #156, though I have in some others such as comment based help arguments.

Ironic because due to a bug, \ is required for relative path imports.

😄 , I don't think that is a bug, I think it is by-design as a defense in depth measure, but definitely ironic.

I might try to look in to improving the 'using' keyword's syntaxing logic. I've done some already for the namespace portion in my PR's, but not for module.
