I was on a similar quest few years ago trying to embed a scripting language inside my app server, after much research I found lua to be the easiest to embed at a cost to programming style, however after using lua for a bit as an extension (an embedded script language) I found it to be just fine, since the function extensions I wrote almost forced structure since the data was already defined in C and merely exposed via lua. Since then I have grown to really like lua (but not as a standalone language). Java on the other hand, while not too difficult to embed, consumed almost 3x the entire memory footprint while executing a simple HelloWorld class. I come from an 8-bit world of 64KB with 8KB used for video, that kind of bloat offends me (not to mention WebSphere using almost 1GB of ram just to start empty). Java had so much potential in the 90s (when it was introduced), but when all those large corps started weighing in with their JSRs and 'enhancements' it quickly became the poster child for 'designed by committee'...bloatware. Anyhow, good read, glad there are other people out there who take memory usage seriously. I can appreciate your quest for a language that lies somewhere between lua and java.

Explicit type declaration should be optional, not mandatory. Type inference isn't exactly new technology. I second this. Explicit type declaration should be optional, not mandatory.

Typed, but no types to type. Boo and hAxe are the only imperative/oop language I know of that do this.
