While functions apply to subjects, modifiers can apply to functions *or* subjects, and return functions. For example, the 1-modifier `˜` modifies one function by swapping the arguments before calling it (Swap), or copying the right argument to the left if there's only one (Self). 2 -˜ 'd' # Subtract from - +˜ 3 # Add to itself + +˜ 3 # Add to itself This gives us two nice ways to square a value: |
