Have another look at it. Does "add" look to you in this context at all like a function that returns void?
printf("1 + 2 = %d\n", add(1, 2))
You were right :/ It's all fixed now, thanks a lot for reporting.
(At first I thought that you thought that return type specification was non-optional, e.g. that it lacked "-> Void")
About the other issues: are you really bothered by them? (e.g. the familiarity of the writing, etc.) I thought it'd be less boring, but I didn't mean it to annoying.
EDIT: fixed the "strange little dots" and "compiler is your friend" parts.
E.g. "Foreaches. Foreaches is like.. a regular For that gave up alcohol, decided to shave daily, and bought a new suit. It's prettier, and more effective. "
I've been programming in C# for years, I know foreach. It's a workhorse feature that I use daily. There are similar constructs in Ruby and PHP and others.
