[Boost-users] [proto] Wrapper compile error

Eric, Here's a message I've owed you for a while. I mentioned a compile error with the ADL example for expression wrappers. I've attached a testcase. Uncommenting the commented bits and compiling with g++ results in an error message which leads me to believe that somewhere in the guts of proto there's an expectation that wrappers have one template argument. Usually this gets solved by using metafunction classes. Or, more likely, I'm just doing something wrong. :) -Dave
