Notes

Be aware that this command 'unwraps' lists passed to it. So, if you pass a variable to it, and you want the variable's contents to be appended without being unwrapped, it's wise to pre-emptively wrap the variable in a list, like so: append [$val]. This way, append will only unwrap the outer list, and leave the variable's contents untouched.
