== operator on Belt.Set does not check if sets have same contents

OK, so the answer is that overriding using \"=" would work for comparisons using ==, but it’s not officially supported, and to use a normal function equal instead.

@Hongbo what do you think of the idea I mentioned in this thread…

@jmagaram

First, help developers not fall into the problem I did. One possibility are decorators @nocomparison and @noequality. If these are on any type the compiler could prevent you from using == and the comparison operators on these types directly or on types (including abstract ones) that contain them. F# does this. Then put these decorators on the Belt Set and Map.

Warning 102 is overly broad. Avoiding use of == everywhere is not practical. Polymorphic comparison generates the expected result most of the time.
