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]
DefinitionsFunctions and types and can have associated definitions. These are accessed by specifying the function or type, followed by a period, and then the definition's name.

pos
Returns the captured positional arguments as an array.
