Hi,
It seems the compiler is not seen it is inside an outer macro. In this case it seems that we need another macro e.g.BOOST_NESTED_TYPENAME. You could try to follow the protocol of adding a new macro andpropose apatch to John.
An other alternative: I suspect that the nested structure is code that you generate with your macros in Boost.Local orBoost.Contract. I propose you to define a nested template
template void f(T& x) { template struct s { T g() { typename boost::remove_reference::type i = 0; return i; } }; x = s().g(); }
Yes, for my application I can use class templates instead of function templates (this is actually not code generated by macros but just a Boost.Local example for the docs that shows how to use BOOST_LOCAL_TYPEOF). I'll leave it up to Boost.Config maintainers to decide if the introduction of BOOST_NESTED_TYPENAME is needed or not. Thanks a lot! -- Lorenzo
