This line is where the reallocation happens. a ~ b on built in 
arrays and slices, ALWAYS allocates to ensure it doesn't stomp 
over some other in-use memory.

~= can extend if there's capacity, but ~ always makes a new array 
without modifying the input. Ali linked to the array article that 
explains the implementation in more detail.


The remove function should copy the data itself instead of using 
the ~ operator if you want it to operate in place.
