LESSON 8

Functions & closures

Create functions with make and return values with give. Calls normally omit parentheses.

Concept

  • Functions are values and can form closures.
  • Low-punctuation calls are a core SE design rule.

Example

SE
make add a b
    give a + b

say add 5 3

make make_adder base
    make inner value
        give base + value
    give inner

add10 = make_adder 10
say add10 5
