Cory,
Is there any specific reason why there is no operator[] const for boost::unordered_map? Or, is that only an oversight?
Like map<>, operator[] inserts if the key doesn't already exist, so a const version won't work. You need to use find().
I see. OK thanks.
There's also 'at' which is like 'operator[]' but throws an exception if it can't find the key. Daniel
