Well, in fact that's what I was trying to do with the \bgroup and the
\catcode's inside \cbgreek; however, it seems that the local \catcode
reassignments don't reach the expansion of \directlua or \scantokens
below; perhaps I need to declare the \catcode reassignments inside the
lua code for lgr2utf, but the documentation is still very terse on
this subject (sending messages to TeX from within Lua or viceversa).
It also occurred to me that the \*catcodetable commands could do the
trick, but I fear I don't quite get the right syntax to set or reset
the catcode tables, or whether the new eTeX primitives still fail to
reach the guts of \directlua.
