Under cases where v2::words live in a packed structure, pointer lookups to underlying integer can be an issue.

It seems that inline methods are happier than external functions such as operator==(lhs, rhs) in this situation.

This implies that inline methods somehow are OK with a mis-aligned this pointer. More exploration is needed:

Use a packed struct of foreign endian v2::word
See if indeed inline methods are that much happier, and if so, why - i.e. doing word math on an off-alignment value one would think would be similarly disruptive regardless of inline method or not, so see what, if any, the difference is
