Well, that leaves us with a few options. (I agree with what you say  
above.)

#1  Leave the naming scheme of tlp/toks/tlist as is
#2  My proposed (and illogical bearing the above in mind)
     renaming of tlp to tlist; leave name of toks as is
#3  Keep tlp; rename tlist to toks
#4  Keep tlp; rename toks to tlist (!)
#5  Either of #3 or #4 but rename tlp to something else
     again (!!) I don't really want to imagine it but you
     could do rlist or something (for "restricted token list")

I think right now I'm happiest with #3 but I also think we need to  
discuss things further...
