I had a pretty simple requirement in my Scheme program to execute more
than one statement, in the true condition of a 'if'. . So I write my
code, something like this:
(if (= 1 1)
((expression1) (expression2)) ; these 2 expressions are to be
executed when the condition is true
(expression3)…

Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here.

I'm trying to create a Cocoa framework by using a cross-project reference in Xcode.
I have 2 projects: one for the framework; one for the application that will use the framework.
This framework is not intended to be stored within the system; it is an embedded framework that lives within the application…

In the past two years, I have been developing .NET from my MacBook by running Windows XP into VM Ware and more recently into Virtual Box from OS X. This way, I could install Visual Studio and be able to work seamlessly.
But, this way of working has a major down side: it kills the battery of my laptop……
