[C++-sig] boost.python automatic policies

[Damien Gleizes]

Hello,

I am currently using boost.Python for binding C++ code. In fact, I'am parsing a
sort of container wich stores all classes I need to bind, including their
methods and members (methods signatures, arguments types). While parsing these
classes, I generates CPP files containing the binding code (wich uses
boost.Python). The problem I'am confronted to concerns the use of policies. Is
there a way to know wich policies to use without knowing what the function
exactly do? Without policies the code does not compile, so I wonder if it is
possible to know wich policies to use just with the decoration of arguments and
return value (types, reference, pointer, const etc). 

Thanks for your suggestions!
