It would be very helpful to have relative matches for LuaJIT. The gmatch iterator in Lua seems rather slow, so it would be nice to have a "relative" modifier to the luajit keyword. One example might be multiple PDF objects that have been compressed using /FlateDecode. We may want to decompress content between stream and endstream. No reason to call this globally once and have lua iterate over the objects when we can do it in the rule lang.
