I saw the changes
remove typedef typename Expr::proto_base_expr
add typedef Expr proto_base_expr_; /**< INTERNAL ONLY
add typedef typename proto_base_expr_::proto_base_expr
This is more or less what I did to fix it manually. I am also glad to
see this trick to get around the problem that for some macroed types
'typename' is necessary and for other it is not (I am assuming that
this is the purpose). What and annoying thing this 'typename' thing!
lately I am putting it everywhere just in case. It is easier to read
the error message of its redundancy than the opposite one.
offtopic: Do you know if this is 'typename' issue supposed to improve
in the next-C++?
