Hi Simon -

It will be easier to help if you have a minimal example of what you are 
trying to do. qi::locals are typically used when needing to store and 
pass state within grammars (rules). If you are trying to "return" a 
value from a parser, that is called synthesis and you can use compatible 
attributes to do that.

Perhaps a description of what you are solving and your rule(s) might 
allow us to provide better information.
