923566c4e9 Get rid of println's for token/ast debugging
Instead just explicitly stick them into the returned string.

This is necessary 'cause I'm gonna convert simplerepl to use ncurses
soon, so I can't have any side effects

f33cfdadfe Fix variable lookup order
Evaluator uses frames as a stack, so to find the most-recent variable
binding we have to iterate through it the reverse way. This fixes a bug
manifested by:

fn a(x)
 x + 20
end

fn b(x)
 a(x) + 20
end
