For BOOST_TYPEOF(this) to work on msvc (MS may fix it in vc10) I would imagine the msvc BOOST_TYPEOF would need to expand to something like:
enum { boost_typeof_local_typeindex__LINE__ = ...expression-that-may-involve-this-to-get-type-index... }; ...expression-using-type-index-to-get-type...
rather than
...expression-to-get-type...
First of all, sorry for misquoting. The section I intended to quote was: The common workaround (capturing a compile-time integer with an enumerator and using the enumerator in the template parameter list) doesn't work with the vc71-specific implementation of Boost.Typeof since it is based on typeid() -- this cannot be captured in a compile-time expression (or I know of no way to that doesn't involve the expression existing in a template argument list). Second, thanks for the workaround. I have implemented this for BOOST_TYPEOF_NESTED_TYPEDEF, so that this can now be used with expressions containing this for VC compilers. Usage: BOOST_TYPEOF_NESTED_TYPEDEF(unique_name,this); typedef unique_name::type this_type; Can you use this in stead? Regards, Peder
