I am also writting my own toy lisp: Muddy Scheme in Tcl. I am planning to implement R4RS and to add all the feactures of Arc (without continuations and with different thread model). I want to try if is possible to have one interpreter with two modes scm/arc, only changing the eval functions and special forms.

Of course It is too slow for real use, It is just a learning tool (I even had to learn how to do the mark and sweep garbage collector).

The code (use only the gc2 branch): http://github.com/pmarin/Muddy-Scheme/tree/gc2

"This interpreter tries to follow the awesome "Scheme from Scratch" articles written by Peter Michaux." I learnt alot from his code too! I thought about doing some thing like "implement R4RS" eventually but figured I should learn a bit more about lisp first. I think its possible to do scm/arc together.. I'm not sure you even need to change the eval function...
