Looking at your and Yichao's responses, I think my definition of Range is poor/wrong. I just wanted a type that denoted every element of the same type between the start and stop point (inclusive). So e.g. an input of (0.0, 1.0) would denote the set of every Float64 between 0.0 and 1.0, and (4,

Sampling only happens with Reactive if you explicitly use the `sampleon` function. Otherwise, you just map a function onto a Signal to get a new Signal. When the first Signal changes, the second Signal changes too. There's no sampling or polling going on in the normal case. I'm in no way

I have a function that computes the unit vector and replaces the input with that unit vector. However, when I have the input as part of a larger array, it doesn't replace that part of the array. For example, if the vector I want to make a unit vector is R = [1. 2.; 3. 4.; 5. 6.], the function
