I had a look... the FractionalThing and IntegralThing classes just don't
take up much space... eventually I wouldn't mind getting rid of them,
but I'll save that for later.

The various *Op.class files take up more than 1K though... hrm.

What's really grown are the various *Cmds.class files.  To some degree,
that makes sense, because the command names have been moved there.
However, Interp.class should have shrunk quite a bit, but it didn't...
not much, at least:

Old:
  -rw-r--r--      5509  22-Mar-2006  22:56:32  org/hecl/Interp.class
  -rw-r--r--      3857  22-Mar-2006  22:56:32  org/hecl/ListCmds.class
  -rw-r--r--      2650  22-Mar-2006  22:56:32  org/hecl/InterpCmds.class

New:
  -rw-rw-rw-      4639  26-Mar-2006  18:58:54  org/hecl/InterpCmds.class
  -rw-rw-rw-      4984  26-Mar-2006  18:58:54  org/hecl/ListCmds.class
  -rw-rw-rw-      4639  26-Mar-2006  18:58:54  org/hecl/InterpCmds.class

I think I may have found something.

When I do javap -c InterpCmds, it shows //String proc (for example)
twice!  I don't understand if that's significant or if it's just javap
giving me funny results...
