element type as long as every element is the same type. This is for
compatibility with older configurations; for new code, we recommend using
the full form.

+ Maps can be made with braces ({}) and colons (:) or equals signs (=):
+ { "foo": "bar", "bar": "baz" } OR { foo = "bar", bar = "baz" }. Quotes
+ may be omitted on keys, unless the key starts with a number, in which
+ case quotes are required. Commas are required between key/value pairs
+ for single line maps. A newline between key/value pairs is sufficient
+ in multi-line maps.
+
+ Note: although colons are valid delimiters between keys and values,
+ they are currently ignored by `terraform fmt` (whereas `terraform fmt`
+ will attempt vertically align equals signs).
* `set(...)`: a collection of unique values that do not have any secondary
identifiers or ordering.
