A hundred years ago, humanity answered that very question, twice. In 1936, Alan invented the Turing Machine, which, highly inspired by the mechanical trend of the 20th century, distillated the common components of early computers into a single universal machine that, despite its simplicity, was capable of performing every computation conceivable. From simple numerical calculations to entire
Input devices (whether physically present, or emulated) may produce any "kind" of input.
In other words there is no clear distinction between a keyboard and a mouse, other than the data they (i.e., their drivers) write to their corresponding /dev/input/eventX file (where X is an integer).
That can be problematic sometimes, for example if a program in userspace consumes input data from a device and expects that data to only contain certain keycodes, event types, etc.
Another example could be a video game which displays different sprites/text when a gamepad is used instead of a keyboard, like key/button prompts in a tutorial or a settings menu.
Luckily, most devices only write a strict set of event types and codes to their eventX file, because well, most hardware is only a keyboard, or mouse, or gamepad, or touchscreen, etc. and not a wild combination.
The kernel calls these the input device's capabilities, as documented [here](ht

This a short overview of some of the things you can do with Ezno today. If you find any problems, file an issue.
The following examples show some errors that have been caught using type checking, partial/const evaluation and effects.
To get started we will install oxidation-compiler which has bindings for Ezno's checker. (you can also get the binary from the releases page).
npm install -g oxidation-compiler@latest
