Functions

All functions can be used as tools. More on this in the chapter on LLMs. Functions can take a docstring, and this will be sent to the LLM as a description of the tool. You can have default arguments...

def round(num:number, decimals:number = 2)

...and variadic arguments

def print(...messages:string[])

Functions also support block syntax.

You can also use named parameters in function calls.

def round(num:number, decimals:number = 2) {
  // body
}

round(num: 3.1415, decimals: 3)

These don't let you skip any parameters, but do make your code clearer and easier to read.
