- Hi there,
Just picked up SICP again and my solution to exercise 4.16 has a
problem. I think I've got the transformation from internal defines to
let+set! correct, but when I attemp to test this by passing my
transformed procedure to the metacircular 'apply', returns an 'ok
symbol, which is the value of the first set! - i.e. it isn't
processing the entire procedure body.
It seems that there is no implicit (begin) implemented in the
metacircular evaluator. Which is all fair enough, but in that case
wouldn't everyone hit this problem?
So...does everyone hit this or have I got something wrong?
[I'm using mzscheme rather than MIT scheme, but I can't see that that
would make a difference like this. Could be wrong.]
