arguments
Captured arguments to a function.
Argument Sinks
Like built-in functions, custom functions can also take a variable number of
arguments. You can specify an argument sink which collects all excess
arguments as ..sink. The resulting sink value is of the arguments
type. It exposes methods to access the positional and named arguments.
#let format(title, ..authors) = {
let by = authors
.pos()
.join(", ", last: " and ")
[*#title* \ _Written by #by;_]
}
#format("ArtosFlow", "Jane", "Joe")
Spreading
Inversely to an argument sink, you can spread arguments, arrays and
dictionaries into a function call with the ..spread operator:
#let array = (2, 3, 5)
#calc.min(..array)
#let dict = (fill: blue)
#text(..dict)[Hello]
构造函数参数参数是传给函数的输入，写在函数名后的括号中。

Construct spreadable arguments in place.
This function behaves like let args(..sink) = sink.
#let args = arguments(stroke: red, inset: 1em, [Body])
#box(..args)
