Map Initializer List

[anonymous]

; For Arrays, we can use
Global $a = [1, 2, 3]
; or
Global $a[] = [1, 2, 3]
; or
Global $a[3] = [1, 2, 3]

; But if we create a Map, it is always empty, and there is no good way to initialize Maps. So here is a suggestion:

Global $a["key1", "key2", "key3"] = [1, 2, 3]

; is the same as

Global $a[]
$a["key1"] = 1
$a["key2"] = 2
$a["key3"] = 3

; I'm sure we do not "need" this feature, but it would be nice to have. (the same argument could be made for Array-Initialization with initializer list... we do not "need" it, but it is nice that it exists)

[anonymous]

; Addition: If the right side is missing, the map is initialized with empty strings for every key.

Global $a["key1", ..., "keyN"]
If MapExists($a, "key1") -> True.

; This enables compact and easy to use string lookup-tables.
