(a: […Any]) → array

Also known as: (array:)

Creates an array, which is an ordered collection of values.

Example usage:

(a:) creates an empty array, which could be filled with other values later. (a: "gold", "frankincense", "myrrh") creates an array with three string. This is also a valid array, but with its elements spaced in a way that makes them more readable:

(a:
"You didn't sleep in the tiniest bed",
"You never ate the just-right porridge",
"You never sat in the smallest chair",
)

Rationale:

For an explanation of what arrays are, see the Array article. This macro is the primary means of creating arrays - simply supply the values to it, in order.

Details:

Note that due to the way the spread ... operator works, spreading an array into the (a:) macro will accomplish nothing: (a: ...$array) is the same as just the $array.
