Pepsi and Coke (No. 3)

A few notes from Ian.

The implementation of "print". The following version would be adequate in the rounded paren syntax. Also, it takes advantage of existing print: method.

(define print
  (lambda (object)
    [StdOut print: object]))

There is "for" construct that uses "syntax". With "syntax", you can define a new syntax called "block". And, with block one could use collect: (and do: and others) in the ()-world:

['(1 2 3) collect: (block (arg) [arg * '3])]

How to write such "block" syntax is left to the reader until tomorrow. (I'll post another entry tomorrow or Friday.)
