I was originally thinking that if the names were remapping into the 
user namespace (with \LuaTeXattribute and so on) there'd still be the 
(admittedly much smaller) chance that there could be a name clash. 
Hence the original use of a char that isn't used in LaTeX2e (the fact 
that I chose _ which is also used by LaTeX3 should be ignored :) ).

I've now changed my mind. At this stage I've prefixed all primitives 
with "LuaTeX" (in keeping with the "XeTeX" prefix). So there's no 
proposed "hiding" any more.

Karl, what do you think of all this? (I assume Taco et al. approve :) )
