Why not use something like `template <class... Strings> typedef booster::function<void(Strings...)> generic_handler;` ? It would fit all needings and has always the right number of arguments. You use it in the map function that are declared with v1_2, which is strange, because you drop pre-c++11 compiler, is that intended (I would really welcome it)?

This is good question. However I'm not going to drop C++ 2003 support:

1. I don't want to break existing code for users that can't upgrade or
do not want to (for example rock stable Linux releases that do not
ship c++11 enable gcc by default)
2. Specific stuff like variadic templates is actually implementable in
terms of C++03 without problems (yes it takes much more code) but this
isn't what would require me to switch
3. I do want to make it more C++11 friendly - for example by adding
move constructors/assignments

There are lots of stuff that can be done by moving to C++11 but if you
do it, it also good to switch lots of other stuff to C++11 (like
booster::thread, booster::regex) but it can't be done fully.
To be honest I prefer to keep it C++03 compatible but with new
interfaces supporting C++11 like move constructors.

You know I really need working hands that can write the code, create
unit-tests, improve the platform and more. But until now I got
very-very few serious contributions.
And when I get them I take them seriously. So it is one man project
because I'm a single person who actually does the job. Also I have
many people who talk about
contributions without actually doing any valuable stuff.

I have no problem giving the access to SF repo as long as I see some
effort, believe me that after several patches i can provide commit
rights to contributors
(subject to copyright agreements

However I hadn't seen too many standing in line ;-)
