Always nice to see Tcl/Tk get attention, it's a language I've often found quite useful. Seems like I'd heard of "L" before in connection with Tcl/Tk, but not sure it was the same thing as Little.<p>Certainly seems it could be a good alternative, a quick look at the syntax makes me think of it like a kind of typed Javascript. The ability to tap into the underlying language, e.g., event loop, Tk UI, coroutines, should be an advantage.<p>There probably is a way to install Little when TclTk 8.6 (and extensions) are already installed (there's a warning about trashing the pre-installed binaries), and not have problems due to moving or replacing existing libraries that applications depend on finding in established locations.
