Please post complete examples to make it easier to investigate suh things.

Anyway, if you don't tell list_of() what type to store in the list, it 
will use the first argument to deduce the type. So you're creating a 
list of std::plus<int> !

do

boost::assign::list_of<BinOperand>( .... )

instead
