fn

This is a callable function.

What it does

A name chosen from a list the program wrote.

What a program uses when a name really does come from outside: the choice

is between things the program named, so nothing outside decides anything.

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.
• & borrows a value for this call instead of moving or copying it.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Result makes success and recoverable failure part of the function's type.
