<font size="2" face="Courier New"><span style="font-family: arial,helvetica,sans-serif;">Right now, I've got a very bare bones Scheme and I'm more interested in algorithms for optimising stuff rather than tools in a specific language. (Also I've just started learning Scheme, and while my current implementation is in Ruby I imagine it will flesh out so I can do more stuff in Scheme directly.) My runtime just lets you start it up in lazy or eager mode; there's no provision in the language itself for delaying execution.</span></font></div>
