Okay, I will try.... :)

        When I decide to write my own Boost.Build v2 on steroids, first of all 
I pick the Spirit as parser, because I knew it. After writing more or 
less complex gramma I hit into slow edit/compile/run cycles. That was 
annoying but I can live with it. But when I hit the gramma debugging I 
gived up. For me debuging was impossible to do in any reasonable time. 
May be I use Spirit in a wrong way, I suppose I am not, but I decide to 
give a try to ANTLR v3. Now I can tell for sure - I will never use 
Spirit for more-less complex gramma until at least it will have tool 
like ANTLRWorks is. I am not a compiler builder expert, but experienced 
C++ developer. I need the tool to solve problems. In that single example 
Spirit doesn't solve my problems it only introduce new.
        Even in Hammer frontend I can't use Spirit I use it everywhere where I 
need a small inline parsing. Before Spirit I have used boost.regex. But 
since I learn Spirit I do not use it anymore. EBNF is much more readable 
for me than regexes.
        That is my experience....
