Abstraction

Operator = creates an abstraction of a part of your program under the defined name.

We can declare a name a and assign 1 to it:

= a 1

We can declare a name b and assign the result of an application c to d to it.

= b (c d)

The transpiler has a special built-in transformation rule for abstraction operator. If you pass more than two parameters to it, it first applies the second one to all of the following parameters and then assigns the result of the application.

So you can rewrite the example above as:

= b c d
