Mediand, std, var to accept function as first argument

Apparently, generators are not quite like map:

Weird behaviour when flattening generator expression with vcat

A very simple example showing this “problem”: a = [1 , 2, 3] g = (a[i] for i in 1:3) a = [4, 5, 6] collect(g) # Gives 4, 5, 6 # Intuitively I would have expected it to give 1, 2, 3 But this is so fundamental that I would be very surprised if it wasn’t supposed to be like that?
