fn

This is a callable function.

What it does

A line written for someone reading it as it happens.

The parts a person scans for come first and unlabelled — when, how bad, and

who — because at a terminal the position is the label. The message ends the

line so the eye can run down the right of the output and read what happened:

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
