Partially-Applied Function with Call-by-Name Params Memoize Values

[scabug]

Consider the following example:

var i = 1
def add(x: =>Int)(y: Int) = x + y
val f = add(i) _

f(1)    // => 2
i += 1
f(1)    // => 2!!!

I would expect the second f(1) to return 3, since the value of i has been incremented. It would seem that the partially-applied form of add (f) is memoizing its call-by-name parameter.
