Pure ESM package

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.

Motivated simulation of GADTs in F#, quite motivational
module GADTMotivation
(*
Here is a simple motivational example for GADTs and their usefulness for library design and domain modeling. Suppose we
need to work with settings which can be displayed and adjusted in a GUI. The set of possible setting "types" is fixed
and known in advance: integers, strings and booleans (check-boxes).
The GUI should show an example value for each possible setting type, e.g. 1337 for an integer setting and "Hello" for a
string setting. How can we model this small domain of setting types and computing example values?
