To make it more digestable, I decided to&#10;break it up into separate parts. This is by no means a comprehensive&#10;study of lambda calculus or type theory, but rather a quick introductory&#10;series so you can can get started. My goal is that, by the end, you will&#10;be able to understand enough to start reading papers on your own and&#10;have some cursory knowledge of type systems. Also, I am targeting&#10;programmers that want to get a better understanding of the theory behind&#10;type systems in compiler design. If you are comfortable programming in&#10;functional languages, then you will start to see many parallels quickly.&#10;Although, I will give examples using an imperative approach to cover&#10;programmers who may not immediately appreciate these parallels.&lt;/p&gt;</description></item></channel></rss>
