[Bug-apl] D-fn binding leackage

[Daniel H. Leidisch]

Hello!

Bindings from inside d-fns/lambdas leak into the global environment:

      x
VALUE ERROR
      x
      ^
      {x←⍵}1
1
      x
1

I didn't read much about this, but as far as I understand, bindings
introduced in these functions are supposed to be lexical locals. Anyway,
this doesn't happen in NARS2000, Dyalog and NGN.


Regards,

Daniel
