Re: [Python-ideas] PEP: Dict addition and subtraction

Does anyone have an example of another programming language that allows for addition of dictionaries/mappings?

kotlin does that (`to` means `:`)   :

fun main() {     var a = mutableMapOf<String,Int>("a" to 1, "b" to 2)     var b = mutableMapOf<String,Int>("c" to 1, "b" to 3)     println(a)     println(b)     println(a + b)     println(b + a) }     {a=1, b=2} {c=1, b=3} {a=1, b=3, c=1} {c=1, b=2, a=1}
