Minor style changes make the review harder as you have to scan for non 
cosmetic changes.

Generally seems okay but:

- why is there no include for allocation.hpp or else 
allocation.inline.hpp when it is obviously used in the cpp file

- why do you not use NULL when checking pointers eg::

  73   ASSERT_NE(i, (Integer*) 0) << "Should find it";

Explicitly casting 0 to a pointer is not good form IIRC.

Otherwise conversion seems fine.

Thanks,
David
