Well, it's time for me to surrender. Sort of :) Raymond pulls out all the stops in his sixth version

First, big thanks for the very interesting series.

Just one thing – I wonder, when you originally wrote the dictionary application, did you actually follow all the steps you’ve shown here? What I mean is, did you start with the pure STL version, and then slightly moved on to what we see now or, for example, the memory-mapped file was there from the very beginning, and you just wrote the STL stream version for the blog's sake?

Sorry, I didn’t ask this earlier but [Raymond was currently on vacation].

The goto is unnecessary -- you can just replace it by throw(OOM) which is about the same number of characters, and put the OOM declaration a bit further up.

To clarify, when I say cast back when talking about reinterpret_cast I mean reinterpret_cast back, you cannot reinterpret_cast to one type and static_cast back to the other and expect that to be work in general.
