This was suggested, which is probably the best:

push_front<1>( cont ,  _data = f, _repeat = n )( 1, 10, 100, 1000 );

More generally,

// Fixed arity:
push_front<I>( cont ,  options... )( a1,...,aI,...,z1,...,zI );

// Variadic
push_front( cont ,  options... )( args1 )...( argsn );

where in each case (fixed and variadic), options... modify the semantics 
of the subsequent calls to operator().
