Probably it is inefficient indeed. The (unless (boundp ... stuff in the above
takes care of that.
Key here (to make it work) is to set local-abbrev-table (which becomes
buffer-local when set) to your snippetised one.
You can optionally put (require 'snippet) in your hook too, just before or
after (abbrev-mode 1). A (require ...) loads a file just once, so it does not
matter much to put it in the hook, plus it cuts down startup time if you put it
in the hook. Or place an autoload like (autoload 'snippet-with-abbrev-table
"snippet") outside of the hook. Then if you define snippets for another
language, you do not have to require it in every other hook.
Actually I have struggled with the snippet code too myself, and your post
reminded me that this was something I still had to look into. So I am no expert
and might be missing something out, and telling you a wrong way to do something
good. Anyway, this seems to work for me.

Apparently, and loving it.
