Confusing wording in Chapter 10 Exercise 6 #21

You say

Suppose you wanted to set an atom’s value to 33. How would you do that? Keep in mind that swap! demands a function, not (say) an integer.

I assumed I just had to add 32 to the current number of 1, so I just did (swap! my-atom (partial + 32)). Only after reading the next exercise did I realize your true intention. I guess what's not clear is when you say "an atom" you mean any atom, not the one just referenced in the example code.

Added "regardless of its current value"
