F# check if 2 maps are identical

Is there any short way to check if 2 maps are identical?

For example

map [("a", 10)]
map [("a", 10)]

-> identical

map [("b", 10)]
map [("b", 11)]

-> not identical

F# uses structural comparison in most cases and there in particular your comparision would be true.

The default = appears to work

>   Map.ofArray [| (1,"A");(2,"B") |] =   Map.ofArray [| (1,"A");(2,"B") |];;
val it : bool = true
>   Map.ofArray [| (1,"A");(2,"B") |] =   Map.ofArray [| (1,"A");(3,"B") |];;
val it : bool = false
