**Lua and Pallene**
Lua is a scripting language widely used in several fields, with
strong niches in games and embedded systems. Pallene is a
companion language for Lua, that is, a system language
specifically designed to interoperate with Lua in a scripting
architecture.
The first part of this talk will present the main features of
Lua, in particular those that set it apart from other scripting
languages: portability, simplicity, and embeddability. The second
part will discuss Pallene and the concept of a companion
language, which brings together ideas from scripting, jit
compilation, and gradual typing, focusing on a design that aims
to bring more performance for Lua programs.
