I am moving from dynamic to static typing. Unfortunately the `compose` primitive has a rank-2 type in the general case, so you need explicit type annotations for many higher-order functions. I am supporting ADTs, which are basically identical to quotations under the hood. There will be an object system in the standard library once I figure out a good object model. Memory management is done through plain old refcounting. Some programs may benefit from waiting for the next push before deallocating popped values, but I have yet to profile to find out. As you may have realised, currying doesn’t really apply to concatenative languages because they lack application. The analogue of partial application is deferred composition, i.e., just concatenating quotations: [1] [+] compose [1 +] = I’ve been working on the language actively, but have
