Hi,

progress, but not enough:

of course this is the wrong approach; I should first lex the string. But 
building a full blown preprocessor every time I need to lex a string 
like "nsp::class" looks a bit heavy. Is there a shortcut? Is it 
Preprocessor::CreateString()?

And the offer below still stands ;-)

Cheers, Axel.
