If you don't declare it as a global, and if you try to assi
The problem seemed to be because I was rebinding result inside

If I understand you correctly, you want `tmp' to be global...

Otherwise, what happens is that you declare a variable local to
execute, that is named tmp. When the assignment occurs it uses the

also I have

and
