4300,"at<AssocSeq,Key,Default> undefined",anonymous,Aleksey Gurtovoy,"the mpl::at overload for associative sequences is documented to be:

template<
      typename AssocSeq
    , typename Key
    , typename Default = unspecified
    >
struct at


but there is no 3-parameter-overload in mpl/at.hpp.

so the following code:
typedef mpl::map< mpl::pair<int,double> > mymap;
typedef mpl::at<mymap,float,int>::type should_be_int;

results in:
'boost::mpl::at' : too many template arguments
