Last time I promised to post these more frequently, and blatantly failed to find the time... In return, I've taken the time to combine what would have been parts 5, 6 and 7, that by themselves would've been annoyingly short. Here goes:
So far our program have only ...
Sorry for the long delay since the last part, I've simply been too caught up in other stuff. As the list from last time indicated, this part will cover defining functions and adding support for building a simple "runtime library".
A programming language without either functions or methods isn't ...
I've seen lots of template systems in Ruby, but haven't been really been happy with any of them. Over the last few months or so I've kept notes of the ones I looked at. This is the list I came up with, and some comments on each. But first a disclaimer:

In the discussion following my entry "Why Rails is total overkill and why I love Rack" several comments raised the issue of whether high coupling is always bad. My answer was that I believe it is, but at the same time it can be worth it sometimes.
