After a little browsing in the documentation, it seems to me that the
LuaTeX function tex.setcatcodes([global,]n,c) is the way to reassign
catcodes for characters inside lua routines, if indeed TeX's catcode
assignments are unable to reach the guts of \directlua calls. However,
without examples I'm pretty much in the dark. Any enlightenment will
surely be welcome.
