Subject: [boost] [parameter] arg_list.hpp depends on maybe.hpp

I've been inspecting my code for a possible compilation speedup. The
code uses Boost.Parameter and thus my attention shifted to it as well.
I noticed that the parameter/aux_/arg_list.hpp header depends on
parameter/aux_/maybe.hpp, which appears to be quite heavy due to its
usage of Boost.Optional and other headers. From the code it looks like
this "maybe" is only related to python binding, and the only thing
arg_list.hpp needs from it is the maybe_base class, which is trivial.
Is it possible to extract this class to a separate header and remove the
dependency on maybe.hpp from arg_list.hpp or am I missing something? The
change looks quite harmless. If I'm not missing anything, am I allowed
to apply the change?
