`AllBeEquivalentTo` works on enums but not on strings

Description

AllBeEquivalentTo works on enums but not on strings. This is very inconvenient

Complete minimal example reproducing the issue

E.g. testing the State property of a collection of objects all have the same enum value I can write

someCollection.Select(x => x.State)
    .Should()
    .AllBeEquivalentTo(StateEnum.Inactive);

Changing field State from StateEnum to string I had to rewrite my asserts to

someCollection.Select(x => x.State)
    .Distinct()  
    .Should()
    .BeEquivalentTo("Inactive");

which is less elegant than using AllBeEquivalentTo

Expected behavior:

be able to use AllBeEquivalentTo with strings

Actual behavior:

compiler error

I see that v6 has been in the works for over a year - when do you expect the final will be released?

Very soon. I’m trying to fix the last bugs and have already prepared a blog post.
