RacketCon Is Saturday
RacketCon 2026 takes place October 3-4, featuring talks on type inference, low-level programming with Pille, and a new FFI (ffi2).

summary
RacketCon 2026 is a community gathering for the Racket programming language. The event includes technical presentations on improving Typed Racket's inference, the Pille language for low-level LLVM-based programming, and the ffi2 library for better C-interop. Other sessions cover floating-point accuracy with Herbie, effect handlers in cio, and immutable dataframes via Uke.
key points
- Pille aims to bring Rhombus-based language-oriented programming to microcontrollers and high-performance domains via LLVM.
- The new ffi2 library combines the convenience of Racket's original FFI with the performance of Chez Scheme's static approach.
- Treason is a prototype language designed to maintain IDE services even when macro expansion fails due to errors.
- Herbie is a compiler that optimizes mathematical formulas to improve floating-point accuracy.

consensus
The thread is thin, but commenters are generally supportive of the event and use the space to share related personal projects.
I've been messing around with a language that I summarize as:
ALOE = Scheme + Smalltalk + Types

Prototype is in Racket.
The author shares a prototype language called ALOE (Scheme + Smalltalk + Types) implemented in Racket, sparking a technical discussion on OO patterns in Lisp.
