Feature Request: Computing the distance/similarity for 2 lists of same length

[thomasryde]

Would it be possible to write a function that computes the similarity between the corresponding elements of 2 lists of equal length?

I am hoping for a ridiculous speed-up of this operation compared to doing it element by element in python. I guess this request would be like cdist() but just for corresponding elements of 2 lists instead of all combinations. Love the library.
