3 Mutable variables Let’s take a closer look at what happens in a language like C, where variables themselves are mutable.

These programs exhibit mutable values: it is possible for a value to change after it is defined. In this class we’ll design a semantics and type system for languages with mutable state. Mutation is an …

Mutable data structures Mutable variables Mutable Data Structures – Mutable Boxes BFAE – FAE with Mutable Boxes Evaluation with Memories In this lecture, we will learn Mutable Variables MFAE – …

We presented a minimal, runtime-enforced, framework for mutable value semantics in Scala. Its design ensures value independence via explicit control over ownership, borrowing, and lifecycle management.

Feb 12, 2026 · In this paper, we introduced Canvas-CoT, a novel framework that fundamentally shifts multimodal reasoning from a linear, immutable text generation process to a mutable, structured state …

Mutable values such as lists and dictionaries have state and can be changed This can be useful in writing programs that are more efficient and more understandable

Adding mutable store requires yet again a significant change in the structure of the rules of the dynamic semantics. By contrast, the static semantics is relatively easy to extend. We extend our language of …
