A start on error reporting.
...
I outfitted `rest` with some error reporting and tried out exception
handling. So far so good.
One issue is that the dictionary is not a persistent datastructure, so
if there was an "inscribe" command (it's not yet implemented for this
Scheme implementation) that might be slightly problematical. (If an
error were to occur in an evaluation that had already entered new
definitions into the dict then those definitions would "survive" into
the rest of the REPL session (or whatever.))
I'll look into persistent dict for Scheme.

Use Scheme symbols for Thun symbols.
...
It seems more elegant that way, but I haven't tested it to find out if
it has better performance or memory usage (yet.)

Symbols for symbols.
...
This shouldn't work yet, because the parser makes Lisp symbols out of
the Thun symbols, but the match expr still has strings. In the REPL
this fails, but in the compiled Joy binary it doesn't fail, the
interpreter interprets just fine.

A crude main loop.
...
I know there are better ways to do this, but I don't know what they are
yet. Maybe a "do" loop? Anyway, this works, although it doesn't catch
errors yet.

The refactor should be a macro but I don't know how to write those yet
(apparently there are different macros systems... ooo la la!)
