Nice Display Bug (not imortant)

I haven't tried it either. LaTeX3 has been in development for over 10 years though progress has accelerated recently. The problem is that it is a vast task that is being written by people like Joseph Wright and Will Robertson in their spare time, so it may be a long time before it is ready. So I haven't got too excited about it!

The question is, how will LaTeX3 deal with syntax errors like the above? One person who might know the answer is the British developer Joseph Wright who maintains a blog at Some TeX Developments
