Dictionary type.
</brief_description>
<description>
Dictionary type. Associative container which contains values referenced by unique keys. Dictionaries are always passed by reference.
Erasing elements while iterating over them [b]is not supported[/b].
Creating a dictionary:
[codeblock]
var d = {4: 5, "A key": "A value", 28: [1, 2, 3]}
[/codeblock]
To add a key to an existing dictionary, access it like an existing key and assign to it:
[codeblock]
d[4] = "hello" # Add integer 4 as a key and assign the String "hello" as its value.
d["Godot"] = 3.01 # Add String "Godot" as a key and assign the value 3.01 to it.
[/codeblock]
