Implement cons* in Scheme

[Katie Burke]

scheme>>> cons* 'a 'b '(c d)
Traceback (most recent call last):
File "stdin", line 1, col 1
RunTimeError: unbound variable 'cons*'

This one is user error, I think. You need parens around it, and as far as I know it only takes two arguments:

scheme>>> (cons 'a '(b))
(a b)

[Keith O'Hara]

You have to call cons like a function (cons ...).

[Katie Burke]

sorry, I didn't realize that it would take out the asterisks.

Also, I got the example code from here.

[Katie Burke]

According to the scheme.com example (cons* 'a 'b '(c d)) should return (a b c d).

scheme>>> (cons* 'a 'b '(c d))
Traceback (most recent call last):
File "stdin", line 1, col 2
RunTimeError: unbound variable 'cons*'

Interesting, then the issue should be "Implement cons* in Scheme", give the link to the reference, and show

1) what you get 2) what you expected to get

That will help make this very clear what the issue is. Thanks!
