yeah, our completion engine does't cache the lookup tables and the  
template instantiations. So I can clearly see that it'll perform  
pretty bad when completing symbols from boost::spirit. I'm prototyping  
an alternative way to represent the lookup tables. It is something  
that we need for our nextgen refactoring engine. boost and  
boost::spirit are pretty good usecase for the new lookup tables so  
thanks for the report and for sure we will test our new stuff against  
the spirit library.

oops! yep, this is a bug it shouldn't show the namespace.

it's in our todo list.

Thanks for the report.
