True enough. I just don't like the fact that the name of ASIS is misleading. 
And of course, a syntax-only tool would be quite easy to create without 
using any fancy interface. (Our syntax checker/pretty printer tool makes 
similar checks [not sure about that one].) A mostly semantic system with a 
bit of syntax mixed in (we do keep a bit of such information for error 
messages, purely semantic wouldn't work either) seems best to me. ASIS 
doesn't have enough abstraction for my taste.
