Hi there,
I've used this metafunction for some time, and it just fitted my need. Recently, I make up my mind to complete it, willing to put it in

Synopsis -------------- can_be_called<F, Sig>
F Any callable type to test, even member-function ptr. Sig The desired calling signature, function-type only.
There is a feature request for this already in Trac, with source code attached.
https://svn.boost.org/trac/boost/ticket/3783
Sadly, it was opened 3 years ago.
Surely I'm aware of this, but I don't think it'd work out-of-box, would it?
What do you mean? If you mean that the attached code needs polish, I guess you're probably right, but it's been 3 years since I wrote it. :-)
That was my first try that doesn't compile, but it's due to the disability in file iteration for local include path on the compiler I used, but it's easy to fix anyway. And some misreading in your code gave me the impression that it won't work properly, but surely it does work :-) Regarding the difference, mine also concerns the return type (it's useful in my case) and capable of member-function ptr (not sure it's useful or not) and may work for some contrived cases...
If your code is polished, has docs, and tests, then maybe you can attach it to the ticket and ping Tobias. If he doesn't respond, then I guess Function_types is looking for a new maintainer, and you could be it.
But I don't want it in FunctionTypes, Functional seems a better place to me and could just become Functional/Can Be Called as other Functional/XXX.
