[boost] [mpl] at for set and map does not match documentation

The map & set documentation all refer to the method "at" as having a default
return value if no match is found, however I can only get the version
without a default to compile and a look at the source at.hpp seems to
indicate this is not implemented. Any help would be greatly appreciated.

boost_1_33_1/libs/mpl/doc/refmanual/associative-sequence.html

at<s,k>::type - works
at<s,k,def>::type - does not compile (msvc8.0)

Many thanks, Paul.
