There are compilers written with editing and incomplete code in mind. 
Clang, of course, performs some at least error recovery, or else it 
would be useless for code completion.

Can we?

I'm guessing Semantic has at most one level of being "less pedantic", 
and implementing several of them, as well as support for those in 
grammars, wouldn't be trivial.
