yeah, that would be magical :-) I not sure such a 
syntax would be good.

something along these lines would be good. I think

insert( months )( map_list_of(1,2), 31 );

should work (because it is list_of<pair<T,U> >). Alternatively, you would need 
to specify that you are using 
pair<int,int> explicitly or use a typedef:

typedef pair<int,int> key_t;
insert( months )( key_t(1,2), 31 );

You have surely found something that could be better, ie, how can we deduce
what list_of should store?. I think it is impossible to do something like that.
