[boost] Re: Passing parameters through functions

template< class T >
void create_and_run() { T t; t.run(); }

template< class T, typename A1 >
void create_and_run( A1 a1 ) { T t( a1 ); t.run() }

template< class T, typename A1, typename A2 >
void create_and_run( A1 a1, A2 a2 ) { T t( a1, a2 ); t.run() }

// etc. ad nauseum; try boost preprocessor library to save repetition for N
args

create_and_run< SpecialObject >( x, y );
