Expect length of a list/sequence asserter?

[drhumlen]

I seem to miss an expect function like:

let list = [1; 2; 3; 4]
Expect.lengthOf list 3 "Must have exactly 3 elements"

If it fails, I expect to see something like:

Expected length to be 3, but: 

[1; 2; 3; 4]

has length 4.

Is there another way to do this or..? Seems like a quite fundamental asserter.

There isn't an expect function for this. It sound good. Could you submit a PR?
