While function should allow arbitrary body #21

This now allows the use of an arbitrary body, as can be seen
in the following test:
```
(set! p 4)
(while (<= p 10)
(print "Pxx: %s" p)
(set! p (+ p 1) true)
)
```
The new approach defines a local lambda, with a random name, and
calls that recursively when the conditional is true.
This closes #21, though we still need to use the three-argument
form of (set!) as our scoping/environment is confused - that is
tracked in #22.

I wrote a quick fibonacci generator like so:
(set! fib (fn* (n) (if (<= n 1) n (+ (fib (- n 1)) (fib (- n 2)))))) (let* (n 0) (while (<= n 10) (do (print (fib n)) (set! n (+ n 1) true))))That
(do .. )feels like it shouldn't be necessary.(Also the scoping issue requiring the fixed
set!call is really starting to get on my nerves; both should be resolved I think - reported separately in #22.)The text was updated successfully, but these errors were encountered:
