I vote to accept this library. The documentation is very nice.

One thing puzzled me though:
(see http://igaztanaga.drivehq.com/unordered/unordered/comparison.html)

"The containers hash or predicate function can throw exceptions from erase"

Under what cicumstances can/should/would I construct a ahsh or predicate 
that throws? I mean, the hash computes an integer, and comparisons reads 
data to determine its answer.

This migth be what the standard requires, but it certainly seems 
non-intuitive. Why not just require that neither hash nor predicates can 
throw?
