I am discribing following sotuation:

void foo(int arg1, int arg2) {...}

void foo(int arg1) {...}

template<typename Params>
foo1( Params const& p) {
    if( p.has(asrg2) )
      foo( p[arg1], p[arg2] );
   else
     foo( p[arg1] );
}
I think it's very convinient to be able to call different overloads of the
same function without using any MP tricks.
