You're welcome.

I've tried to isolate the reason why the code fails.  See if the 
following change doesn't avoid the problem:

//#define AS_WITH_ID
   auto as = [](auto p)
     {
     #ifdef AS_WITH_ID
       return x3::rule<struct _>{} = as_parser(p);
     #else
       return p;
     #endif
     };

In a much simplified version of your code, when this is run, compilation
succeeds; however, when defined(AS_WITH_ID), then the compilation does 
*not* finish after 5 seconds.

HTH.

-regards,
Larry
