Simon Forman 6e6e52d206 Don't assert defs twice. 
Each definition is getting parsed with the name of the next one as part
of its body, then the next one fails to parse and the thing backtracks.
So each definition (but the last) gets asserted twice.

    def(--,[1,-,?])
    def(--,[1,-])
    def(?,[dup,bool,++])
    def(?,[dup,bool])
    def(++,[1,+,anamorphism])
    def(++,[1,+])
    def(anamorphism,[[pop,[]],swap,[dip,swons],genrec,app1])
    def(anamorphism,[[pop,[]],swap,[dip,swons],genrec])
    def(app1,[grba,infrst,app2])
    def(app1,[grba,infrst])
    def(app2,[[grba,swap,grba,swap],dip,[infrst],cons,ii,app3])
    def(app2,[[grba,swap,grba,swap],dip,[infrst],cons,ii])

...and so on.

Simon Forman 1ecb5be278 Change back to CLP(FD) semantics. 
Minor changes to parser to make it less logical but a little firmer.
(E.g. ints can't be backtracked into becoming symbols!)

Simon Forman eb591d27e0 Debugging this sucks. 
Even with the RISC emu GUI.

Redesign vm?  Add more tooling?  Use MetaII?

Happy Thanksgiving!
