If he provides proper tail-recursion or even a switch statment you can implement FSAs quite easily. Clearly he has a lot of enthusiasm but I don't understand why he is squandering it on implementing boring old language ideas. Why not a language for mashing tree structured data or graphs or for parallel programming or modelling physics of real objects or something. He'd learn even if he fails. Hoare's 1973 paper "Hints on Programming Language Design" might be relevant to what he is attempting (look for STAN-CS-73-403)
