(+= <view on list> blah)
will add the specified elements to the list

(+= var val)

will modify the content of var according to val. In all cases, we need to evaluate the first argument, without any alteration on readability/writeability and call the resulting expression with the add peratior.

To redefine the variable entirely we need to use define.
