at<AssocSeq,Key,Default> undefined

[anonymous]

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
