Re: [boost] [proto]How to for_each on children?

However, I'm still getting compile errors:

extend_transform_xmpl.cpp:142: instantiated from here extend_transform_xmpl.cpp:59: error: no matching function for call to 'arg_c(const xmpl_expression<boost::proto::expr<boost::proto::tag::terminal, boost::proto::args1<arg_id<1u> >, 1l> >&)'

I'm not sure if I parse the error message correctly, but I think you have to instantiate arg_c with the index. E.g. arg_c<0>(expr). Regards, Maurizio
