I just did svn update for trunk, and then grep'ed for can_be_called; however, nothing turned up. Also:
http://www.boost.org/doc/libs/1_42_0/doc/html/proto/reference.html#proto.ref... ce.classes I believe that the docs are just using it as an example rather than adding it to the library. See the following thread where Rutger gives a good implementation using this approach (certainly better than my version). http://old.nabble.com/-traits-function_types-generic--Can-F-be-called-with- %7Ba0,-...,-aN%7D--td27760559.html Also see the comments on the limitations: This approach and code does not seem to work with function objects from: boost::lambda, boost::lambda::bind, boost::phoenix, and my implementation of std::lambda under MSVC. If anyone can figure out a consistent way for 'can_be_called' work for all of these different objects, it would be a great addition. And for Phoenix3, maybe support could be added for this type of operation? I had previously asked about this http://groups.google.com/group/boost- list/browse_thread/thread/8e54612df8c92671/b4b9dcaa91f61094?lnk=raot but ultimately failed to figure it out.
