Almost have lambda working.  It creates functions but they are not evaluated correctly.
Cant get lambdas working.
Add adopt instruction.
Almost have it working again.
Basic eval working avain.
Next step is fixing lambdas calling other lambdas
Make bind throw on duplicate bind in same env.
Eval and lambda work, but dump a bunch of debug info.
Some eyeball testing.
Ok! Lambda is working nicely now.
Lambdas work!
