William Lieurance commented on TAMAYA-345:
------------------------------------------
I did a quick survey on how various of the most popular current languages
define maps. Here's what I found:
* single colons \{"key":"value"}
** javascript/json https://www.w3schools.com/js/js_objects.asp
** groovy http://grails.asia/groovy-map-tutorial
** golang https://blog.golang.org/go-maps-in-action
** python https://docs.python.org/3/tutorial/datastructures.html
** swift https://developer.apple.com/documentation/swift/dictionary
* rocket \{"key" => "value"}
** perl https://perlmaven.com/perl-hashes
** ruby https://ruby-doc.org/core-2.1.1/Hash.html
** php https://www.w3schools.com/php/php_arrays.asp
* singlerocket \{"key" -> "value"}
** scala https://docs.scala-lang.org/overviews/collections/maps.html
* comma, basically an array conversion [("key", "value")].somefunction()
** Java, sort of? It really wants you to call .put(key, value) over and over.
** Rust https://doc.rust-lang.org/std/collections/struct.HashMap.html
** C#

Based on that, I'd recommend going with the single colon. I've submitted
https://github.com/apache/incubator-tamaya-sandbox/pull/9 to show what that
would look like, changing the tests and docs. Totally willing to hear
alternative ideas. :-)
