That'd be nice indeed. As part of the 0.5 release I have just published, I split the language core from the standard library to ensure the former remains as small as possible. So far, it's at 2,500 lines of non-test code and about 480kb compiled. Not the tiniest, but not too huge! (I know, possibly still huge for microcontrollers, but I'm not too familiar with that domain.) As for a book... yeah, that'd be nice too. I attempted to write some worksheets earlier with screen-related concepts (rows/columns, cursor positioning) but, well, uncovered enough bugs at the time that I had to put those in the back burner ;) I'll keep thinking about this though, as a few individuals have also asked for something similar.
